good evening, Celticus, The 240-270 lighten strike are from the hiryu using Grasping Claw to lower the targets phy resist.. then the added bonus damage from it being at all 120 skills.. when those 2 over lap ya will see some truly high numbers.. it also buffs the armor ignore too.. Moves that are built into the bush AI will see a nice increase in effectiveness(like feint,D stance, evade, conf, Whirl,LS) as ya reach 120 as well.. You will see the AI of bush get super defense if you pet drops below 50% until it evades, and conf.s its way back to the 80% mark.. then it gets abit more offensive again.. Sadly the Lighten strike will not stack and fire the same time as a armor ignore.. but they can fire back to back to each other for some impressive burst...Bush as a whole kind of saves mana.. as the moves for it are far cheaper on mana Vs other schools of magic.. so when it fires off a few bush chains moves it allows your pet to regen mana back for the more costly moves like armor ignore... Hope this helps, Mate.. if ya have any more questions feel free to ask. =^-^=
