An effective build that can kill any boss in the game, has no trouble with mapmods, clears with a decent speed, can farm the labyrinth pretty safe and all that on a low budget.   
It´s also one of the best Leaguestarter around.    
Don´t get me wrong, you will find builds that clear maps faster or run the labyrinth faster or kill a boss faster, but many are focused on one part or need a heavy currency investment. This build can do it all.     
The Build is based around the Berserker Class with Bloodmagic.     
Soulmantle, Kikazarus and Self-Flagellation are used in this build.
Pros & Cons:
No gear requirement, can be done with full rares. But one or two specific uniques are not bad. Very Cheap.      
Can do almost every mapmod    
Most of the Damage comes from the Skilltree and Jewels, which are very cheap for this build.     
Can played as a Magic Finder, High Damage or Tanky Character.    
Great Leaguestarter with little gear requirements    
High Tier maps viable    
Can do any challenge and boss in the game    
medium clearspeed, could be faster but also slower    
Hard to see groundeffects like Flamebearers    
Totem RF casting may be too delayed in really good Partys.     
Annoying against some fleeing Enemys.    
RF totems of different player dont stack.    
While being a good Leaguestarter it has a slow start until ~lvl 25    
Hall of the Grandmaster cannot be run, the only map thats basically impossible. The reason is: Totems are getting oneshotted by chaos damage grandmaster   
Bandits:
Kill all bandits and grab the 2 skillpoints.
Its the most flexible choice.
Pantheon:
Major God
Soul of Lunaris is on its own not so strong, but after capturing Lycius its very powerful for any totem/minion build. Avoiding projectiles that chain counters one of the biggest weaknesses of totem builds. besides that it offers some mitigation here and there. solid.       
Soul of Brine King is the best with not a single soul captured. It prevents stunlocks which can be very nasty and dangerous. Isn´t that useful with a high hp pool.    
overall all major gods offer something useful and we can switch around like we want. Solaris is a good choice for atziri and against critmaps.     

Lesser Gods

Soul of Ryslatha is the most solid choice. "Life Flasks gain 3 Charges every 3 seconds if you haven't used a Life Flask Recently" is nice for labyrinths or long bossfights.    

The upgraded "60% increased Life Recovery from Flasks used when on Low Life" is great for emergency flasking, basically everytime we need to use a flask.    
Soul of Gruthkul is ok as well with "+5% chance to Evade Attacks if you've taken a Savage Hit recently" and "1% additional Physical Damage Reduction for each Hit you've taken Recently up to a maximum of 5%" and fits well to the Lunaris Major power. The upgrade is pretty bad.    
Soul of Abberath fully counters a mapmod, burning ground explosions and eventually even burning traps in the lab.    
Jewels:
Spire of Stone is a very good jewel for this build. It gives a good chunk of Totem Life and Stun Immunity for Totems. With this the Totems cant be interrupted by stuns while casting Righteous Fire.    
Self Flagellation is a stable if we have a soulmantle and Kikazaru. it grants 10-20% increased damage per curse on us.     
Fill the rest with rare Jewels, those stats are important:       
- Totem Life    
- Player life    
- Burning damage (new)    
- Fire Damage    
- Totem Damage    
- Damage over Time    
- increased damage       
optional:
- Area Damage (only increases Righteous Fire, not Searing Bond)    
- Player Resist    
- Rarity    
- Dexterity    
Totem life is still the best dps stat for Righteous Fire Totems, but Burning Damage (has a 16-20% roll) grants more overall damage if we include searing bond.

Tips:  

Keep an eye on your elemental resistances and life. If you have trouble with your defence this is often the mainreason            
upgrade your flasks. Higher tier lifeflasks heal more so use them.             
dont be shy pressing the utility flasks when they are off cooldown and you see monsters. They refill quickly ;)             
dont kill every single monster. I rather kill 5 mobs with 1 left and move to the next pack than wasting the time to kill the remaining monster.             
kill essence monsters. even essences with stuff like minion speed can be used on items for a chance of a decent rare item. One fixed bad stat can still result in a decent item while leveling            
medium life, decent armour, 30-40% firedamage and freeze/chill immunity after using a fireskill (any totem). A good mix of Utility, damage and Defence. The Chill Immunity is awesome for Chilled Ground maps as well.    

A Rare Helmet with Armour/Life/Resist/Rarity - preferable with a useful helmet enchant - will be defensively stronger   

Recommended Gears:
Helm 

Hrimnor's Resolve Samite Helmet medium life, decent armour, 30-40% firedamage and freeze/chill immunity after using a fireskill (any totem). A good mix of Utility, damage and Defence. The Chill Immunity is awesome for Chilled Ground maps as well.

A Rare Helmet with Armour/Life/Resist/Rarity - preferable with a useful helmet enchant - will be defensively stronger        
Body Armor

Soul Mantle Spidersilk Robe  Its the prefered chest for raw power (explained in the Informations).Until this use a rare chest with life and resists or a Tabula Rasa        
Gloves

Rare Gloves with Life, Resists and Armour.
Boots 

Rare Boots with 30% Movementspeed, Life and Resistance. After that look out for Armour
Weapon

Doryani's Catalyst Vaal Sceptre

Doryanis Catalyst is a stable in the build.
Rare Sceptres with Firedamage% and Burning damage% CAN be better than a doryani if other stats are useful as well. Keep your eyes open for those!
Besides Fire/Burning dmg we look for stuff like attack speed (faster shield charge), mana, manaregen, castspeed or spellcrit. (you cannot get it all)
Do NOT get any added fire damage for spells on you weapon or other gear!!! It will increase enemy resistances with Elemental Equilibrium!
Shield

Lioneye's Remorse

Tons of life, armour and Block. If you have capped resists without a shield its a great choice!
Then we can use a Rare Shield with high Armour, Life and Resists. Especially useful if you want extra chaos resistance.
Ring

Kikazaru Topaz Ring

Before those just use Rings with life and resistances. Mana and manaregen are good as well.
Amulet

Rare Amulet with with Life, Resists, Dexterity, Firedmg%. Especially Dexterity is important to level Gems.
Flask 
Catalysed Divine Mana Flask (seems the best, but other choices might be better)
Quicksilver Flask of Adrenaline - Experimenter's, Chemist's and Perpetual all work
Granite Flask - Experimenter's, Chemist's and Perpetual all work
Chemist's Basalt Flask
"of Staunching" removes Bleed and has to be on one flask
"of Heat" removes Freeze and has to be on one flask without Hrimnors Resolve
"of Grounding" removes Shock and can be helpful
"of Curing" removes Poison and can be helpful
"of Iron Skin" grants 60-100% armour an can be helpful
Remove the Mana Flask if you use Bloodmagic.
Additional useful Flasks are:
Sulphur Flask for a damage and liferegen bonus
Amethyst Flask if you have problems with chaos damage
Bismuth Flask can be useful if all resists are bad
Topaz, Ruby and Sapphire can be swapped in for encounter with high elemental damage
Silver Flask for more speed
For Unique Flasks we can use:
Laviagnas Spirit - high mana recover relatively quick. Lets you use all skills while OoM.
Blood of the Karui - Recover much hp in a short time
Forbidden Taste - heals you for 75-100% hp instantly. Great panic flask!
Witchfire Brew - to curse without using orb of storms and 50-70% dot dmg
Rumi's Concoction - for armour, block and spellblock
Any of the Utility or Unique Flask can be swapped in for your needs, just keep something for bleed and Freeze removal!
