Forum:Vanir vs Celesta

Vanir gives +40 pierce resist...or up to +4% defense in PvP (negated if atacker has pierce), but wiki page on Vanir (and Aesir for that matter) is not clear on what stat number the bonus % is applied to. Trying to calculate whether Celesta's +49 defense when attacked is higher or lower that the potential +4% bonus from Vanir, to figure who to get/develop, short and long term.

The bonus % applied to my base defense is a much lower number than as a % of my effective, or eDef number (which uses the 70% rule of adding 70% of my base att + gen +rune to my base defense to get my effective def number.)

Ex. My base defense is 600 (no rune added). Assuming no piercing is used on me and I would get +4% from Vanir...this adds +24 to my def. If using 4% of my eDef however..which is 1500, that's +60. (1500 x .04 = 60) Celesta @ level 15 = +49 when I'm attacked.

So: Vanir (lvl 4 no crystal improve) and 4% of base def = +24 def

Celesta @ level 15 = +49 def when attacked

Vanir (lvl4  no crystal improve) and 4% of eDef = +60

Getting Vanir and leveling her to 4 is way easier and faster than waiting for crystals and mega energy/stam to level Celesta. However if Vanir's bonus is on the eDef, then will get better defense immediately and worth the purchase, because that % def number (of +60 at the time)  will only go up and always be higher than Celesta topped out. As eDef number rises..so does the value of %. To equal +49 thru Vanir..I would need to have a base defense number of 1250 to get +50 bonus defense (1250 x .04 = 50) meaning I'd have to acquire an additional 650 skill points( to my already 600 to reach 1250), which takes a very long time, compared to the time and energy needed to get Vanir to level 4.

So.....what stat is Vanir's +4% using? ( Same formula for att bonus from Aesir, applied same way)
