Anyone who says it doesn't exist, you have no imagination, you can have up to Trans-up 15.
I know how to mod every stage/ level, add effects to each stage, change colors, change what stages use trans 1 mesh & trans 2. literally do a full custom anything on Trans-Up.
Example: Trans-up could start at any level you wanted, go to level 15 in the skill menu, have a different colors & different effects around certain parts for each level. So say you started at level 60 and then 70, 80, 90, etc all the way to 200, each stage can easily be changed to give different stat boosts as well.
P.S, I can also mod Argate glow effects & socket glow effects (haven't done any actual skills yet, but it's possible & I'm hoping to do it soon). really any effect anywhere, takes some fiddling but it's all in there some where hahahaha
Oh & the trans-up 3 used in most p servers isn't even set up properly/ optimally, it works, but it's gross, i cleaned it up. XD
(&& before anyone shoves it down my throat that it's easy, lets see you get poison dripping from a weapon, a blizzard for ice, static for lightning, etc. & add/ change layers/ change direction for argates enough to make it have it's normal effect and another on top like runes that glide over the surface in the opposite direction. and adding different kinds of bursts and lights to trans-up. a simple example of using the trans-2 upbursts on the trans-1 model for level 3, then turn them off for level 4 with trans-2 model then back on again for level 5 just for some variation, but really there's infinite possibilities)
