[@Jerkchicken] Thanks for the criticism – I'm sorry my explanations didn't cover everything. I suppose part of the issue lies with the tabletop tag. It was the closest thing that was available when posting so I stuck it on. All of the mechanics and inner workings draw from the root of the Final Fantasy Tactics games. A random number generator is involved in a lot of the calculations – rather than creating complex formulas, I opted to go with percent chances. Having damage represented in percentages mostly makes it easier for me to scale enemies and put costs on skills. Unless a skill includes variance, I know exactly how much damage/healing/etc a skill will do at any given time and can adjust when creating enemies.

As far as the math goes, damage formulas are fairly simple. I'll use your ability [i]Claw[/i], a general physical unit's level 1 stat pattern (25HP/15MP/4Atk/3Def/1Int/2Spr), and a general starter enemy stat pattern (15HP/10MP/4Atk/1Def/1Int/1Spr) in this example:

Rio uses Claw on Enemy unit! 4 Damage (4 Atk x 1.1 [110%] = 4.4 Damage –> 4 Damage)

Enemy unit takes 3 Damage! (4 Atk - 1 Def = 3 Damage)

HP: 12/15

In essence the formula comes out to: (Player Stat x Damage Percentage) - Enemy Stat = Damage Taken

Obviously this can be shaken up. If you look at the example profile I posted you can see the formula gets tweaked with her B-Ability activated. For reference here is the ability:

+Glyph Augmentation – Alters key parts of glyph construction for a short time in order to assault targets with the force of their own will. The user's skills deal damage mitigated by the target's physical defensive stat for Three Turns upon activation. In addition to this effect, 30% of the target's magical defensive stat is added to the user's base damage for the same duration.

Using her stat spread (15/25/1/2/4/3) and her ability [i]Fyr[/i] with [i]Glyph Augmentation[/i] active against the same Enemy, the formula gets additions:

Cerys casts Fyr on Enemy unit! 6 Int Fire Damage! AUGMENTED!! ((4 Int x 1.3 [130%]) + (1 x .3) = 5.5 Damage –> 6 Damage)

Enemy unit takes 5 Damage! (6 Int - 1 Def = 5 Damage)

HP: 7/15

Cerys' B-Ability shakes up the formula by adding in a component – factoring in additional damage based on her opponent's stats. This is readily available in abilities and, potentially, equipment. There are also other factors such as critical hits (x1.5 Damage without a skill/ability that augments) and elemental weaknesses/resistances (x4, x2, x0.5, and x0 respectively).

I was going to use the practice battle to explain most of this, but this will probably help in creating your characters. If you have any other questions please do not hesitate to ask!

[@AlternateMan] If it's a buffing move for the D-Ability, I think the damage might be a little much. And toward who? The allies or enemies? I also think a 50% boost would probably suffice. 100% is just a little too much for three turns, even as an ultimate ability. Also tagging you in case the above info is helpful to you.

[@Lauder] Just tagging you in case any of this info is useful.
