Detonate Dead

Thx guys. Vipermagi used some hard words but I think I now know:) So PA won't work but the weapon will.

Main idea is low life ES MF build to play with friends. In details I think I can choose one of two ways:

First option. Passives with iaoe, ele and fire dmg.

Gems:
Detonate dead + Culling strike + Increased Area of Effect + Concentrated Effect + Life Leech.
I'd like to use fire penetration but I dont have idea which gem should I kick out and for now I can't afford to 6l my shavronnes.

Weapons would be: 2 x Redbeak or 1 x redbeak and es shield.

Second option. Passives with as higher but more on burning dmg.

Gems:
Detonate dead + Chance to Ignite + Elemental Proliferation + Increased Area of Effect + Fire Penetration OR Increased Burning Dmg

In this case burning dmg would be the most important so I guess The Searing Touch should be my choice.

I haven't done any maths yet, but I'll. Any further suggestions would be very helpful!:)

your second build(?): or similar. needs at least 15% extra increased spell damage from equip and flammability curse.

I got one more question - I've started maths:)

Assume that I've got:
1. passives
+78% increased fire dmg
+56% increased elemental dmg
+20% increased aoe dmg

78%+56%+20%= 154% increased dmg

2. gems (option nr 1 without culling strike and with fire pene)
+69% more dmg from concentrated effect
+35% more dmg from fire penetration (I know it's much more complicated but I think I can assume that)
+10% increased dmg from fire penetration

10% increased dmg

3. items - 2 x redbeak
+200% increased dmg
+15% increased fire dmg (amu)

2 x 100% + 15% = 215% increased dmg

Total bonus:
154%+10%+215% = 379%

Base detonate dead dmg is 18% of monster life and assume that it's got 5555 hp so 18% is 999,9. Let's assume that that it's 1k.

1000*4,79*1,69 (concentrated effect)*1,35 (fire penetration) = 10928,39

In other words I'll deal dmg near 200% monster hp.

I think it's to good to be true, so where I made a mistake?

lets not try to even bother with a real number, keep it in a percent.

0.18 [the damage percent of corpse's hp] * 4.79 * 1.69 * .6 (what fire pen really does, or (1 -.75) +.35) = 87.92 % of foe's hp in damage.

edit: oh god the forum text just ate half my post...

Soul4hdwn if u use 0,6 as fire penetration it will actually decrease dmg. Is it right? It decreases resistance, so increases dmg. Shouldn't u use 1,35 or some numer increasing dmg with +1?

a resistant mob is 25% damage taken from fire damage.
a non resistant mob is 100% damage taken from fire.

with fire penetration of 35% then makes:
resistant mob takes 60% damage taken from fire damage.
non resistant mob takes 135% damage from fire.

i much rather calculate things based on the weakest situation.

Ok so it would be 87.92 % dmg if mob got maxed resistance and I use FP to low it to 40% OR about 200% if it does have resistance 0% (after FP -35%). Yes?

yes

Do any of you level detonate dead past level 1? Is there a reason to?
