[3.2] Cocotheone Righteous Fire - Life Build - 14k hp 4.3k hp reg 800k+ dps - Deathless Shaper

Let's count the % (as you have about 17% from your numbers which is ok)

- Chieftain 5 minor nodes all with 0.5% life regen = 2.5%
- First 4 whell of passives from marauder has a point in bottom part with 0.8%life regen = 0.8%
- Warrior's Blood 1.8% life regen = 1.8%
- Master of arena 1% life regen = 1%
- Golem's Blood 1.6% life regen = 1.6%
- Arsonist 1% life regen = 1%
- Combat stamina 3 points with 1% + 0.3% + 0.5% = 1.8%
- Sanctity and 3 points to the right of it towards templar starting area 1% + 3x0.4% = 2.2%
- Shaper and 2 points to the right towards scion 1% + 0.3%+ 0.4% = 1.7%
- Quick recovery 0.8% = 0.8%

That will give a total of 15.2% HP regeneration. Now on top of this comes lvl 21 Vitality that will give 1.8% HP regen with empower lvl 3 (linking PoF 21 + Vitality 21 + empower 3 is best setup, as both auras will benefit from empower and PoF at lvl 23 gives +5 max fire resist).
So we have now 15.2 + 1.8 = 17% HP regen. With a sone golem we can add 110 HP regen /sec + Rise of the Phoenix +6HP = 116 HP regen /sec (add here if you got HP regen from any other equipment).
Some of us are using necklaces with %HP regeneration like or those marble necklaces which give only 1.6%. This will bring the HP regen to 19% + 116HP.

This is the hideout regeneration you see at every high level RF character. I have a regen of 2638HP for a total life or 13240HP (19.92%).

Then is the HP regeneration on maps. You get the Ramako point in chieftain and the point left to the Stamina passive under Barbarism which gives you 0.5% + 0.2% HP regen for each Endurance charge = 0.7%.
How many endurance charge you got? Usually about 7 of them (3 base + 3 from passives + 1 from Oak merciless) = 4.9% life regen with all endurance charges up. This you will see again usually at each character.
Some of us have a glove enchant which is called "attack with commandment of light when you take a critical strike". This enchant drops consecrated ground (same as sulphur flask) which give aditional 4% HP regen).
Coco's screenshots are from some patches ago when this enchant was giving some 20 or 24% HP regen - can't remember exactly but is not the case any more).

So we get 4.9% + 4% = 8.9% more HP regen on map.

Here builds start to differ between various players:
- some use the blood dance shark skin boots like this which will give you another 4-5% HP regen depends on how many frenzy charges you got.
- some use normal boots with this enchant which gives 2% life regen when hit.
- it is even possible to use gloves like this if you got a hysteria helmet (those with 30% more elemental damage).

In the end I got 4800 HP regen maximum on maps for life 13240 (36.25%) which is made from 19.92% + 6 EC*0.7% + 5 FC*1% + consecrated ground 4% + enduring cry 414 HP (you can see all details in my RF build thread on forum).
Is exactly how coco's picture were made long time ago, with all effects up, when the enchant was working differently.
Do I get this HP regen all the time? No way. I am not spamming EC or consecrated ground on maps. Usually you will have the 19.92% + 6-7 EC *0.7 + eventually 2 % from boots. = 26.8%. This is more than enough to do maps safely.
