Physical Evasion
Agility 0.1
Strength 0.06

Magic Evasion
Intellect 0.1
Wisdom 0.06

Thanks guys, this makes more sense now.

Now all I've got to do is figure out how much m.eva int gives and likewise for eva and agi and see if full all stats is better that using the eva cards

If that's true, then I made 1 major wrong assumption about derived states. Definitely severely reduces the importance of getting non-base stats and an odd way for the game to handle it since many items directly give derived stats. Good to know though, not stuff I usually worry about.

Percentage increases need to be added together first of all and then applied to the stats you get from pure stats like Power (Strength), Agility, Intellect, Wisdom and Stamina., or ofc, All Stats which is all of them.

Stats such as All Atk, Physical Attack, Magic Attack, Max HP are generally not affected by percentage bonuses.

As an example, if you have a title or costume that has 10% Defense on it, you would take the Defense you get from Power and Agility and apply the 10% to that. Any Physical Defense, Magic Defense or All Defense stats you have on gear are not used in the calculation. If they were, percentage bonuses would be completely overpowered since you generally get much higher numbers with those.

As Kage said, it's quite difficult to calculate what you will get because you can't generally see what your base stats are because the character info window shows total stats (the base Agi, Power, Int etc. + things like Physical Attack, Physical Evasion, Magic Evasion, blah blah blah) - so you would need to go through your items and add them together.

The best title depends on what gear you have and how you card it really. I would lean towards Agile for a mail user for PvP.

This really is a loaded question. Percentages are very complex. It's been a long time since I've worried about this stuff.

As screwup said, percentages are based off of your base stats (though some buffs and added effects are included, it depends on what the buff does).

Base stats are additive and the percentage boosts to those stats are additive. But then there are the stats based on base stats, such as attack, heal, evasion, defense. These stats are affected in several ways including being derived from your base stats (power/stam give 1.2 p.def, agility gives p. eva, int gives magic evasion, etc), they are directly increased as a stat (+2000 physical def), sometimes they are a percentage stat that is increased as stat (might say plus 25% evasion and give you 250 evasion stat for a direct 25% increase), they can be increased by an actual percentage like that title implies (which base int should add to the base m. eva stat and any actual m. eva stat added in, before adding the percentage bonus to it [which itself is additive with other percentage bonus from that stat]), buffs for direct base stats (and passives) should add in directly before percentages are applied and percentage based buffs should add up with other percentage bonuses when applied. I feel like i'm forgetting something else...

At least that is how I think it all operates.

Anyways, it all intermingles in one huge complex system, which makes it rather difficult to actually calculate what it should be. There is a chance that it is off, but I'd rather hope it is working right and you just don't know your actual base that it is operating off of for the magic evasion stat (it is honestly rather hard to figure out pure base of a derived stat (or any stat for that matter) sometimes, particularly when there is a passive interfering with it).

I would take this as absolute but i think percentages are based off you base stats ( without buffs or added effects) as for title depends on what sort of build you want to go for hence why they have different stats.
