Damage range <-> crit conversion?

Trying to figure out which rings I should be wearing, but I don't know how to calculate the usefulness of Crit rings vs. ordinary rings.

What exactly does Crit % do, specifically for a Hero? What does Min Crit Damage do?

[spoiler=If you want to do the specific case's math]
These are the rings I'm currently wearing:
- Explorer's Critical Ring (old one. 2 attack, 10% crit rate, 10% min crit damage (which might not be working?))
- Evo Ring III (10 all 10 attack)
- Absolute Ring (18 all 15 attack)
- 4 att 15% str Tempest Ring

Rings I have but haven't transferred/equipped yet (so can leave them for other chars):
- Pivotal Ring (3 att, 15% crit, 5% min crit damage)
- 2 att 6% str Unleashed Ring

Total att (buffed): ~600
Total crit: 48%
And the question is: which rings should I be wearing?

Well, I did a comparison for Dual Blades here: http://www.southperry.net/showthread.php...ost1181162

I can probably do something similar for Heroes in a little bit, once I read up on all the Hero skills, but you'd probably know them better than me, the math's all there if you'd like to do it yourself rather than waiting for me. (Oh, but you'd have to do a weighted average for average crit damage, which wasn't necessary for DBs since they basically have 100% crit)

Heroes perform badly on crits - Combo Attack (+120% iirc with 10 orbs & hypers) is additive with crit damage so they do way lower crits than most classes. Basically regular hits are 220% and crits are 250~270%.

I know Crit is less useful for Heros than for other classes because of Combo Attack, but I don't really know the numbers. That's why I asked what Crit % and Crit Min Damage do for Heros.

As long as you know your base crit rates, you can work out the bonus due to crit:
(min+max)/2*rate
eg. (30+50)/2*0.4 for a 40% critrate with no bonuses = 16%
+10 min +10 rate (iirc the better ring) puts that at (40+50)/2*0.5 = 22.5%

Just tag that onto the full orbs combo amount - 236% and 242.5% damage. The difference is a 2.75% increase.



If you don't know the actual min/max you can assume they're 30&50 and it won't change much.
