Required Level of an Upgraded Item = required level of the new base item (i.e. Double Bow OR Trellised Armor = 25) -Or- required level of the socket choice (i.e. a jewel, gem, or rune) + 5
So, an up'd rogues bow unsocketed = 30, double bow = 25 + 5 for upgrading = 30. This will be the same as long as you socket it with something that required level 0-25.
if you put in a shael rune tho, shael rune requires lvl 29. so the new level req = 34, 29 + 5. the shael overrides the "base level requirement" and 5 is added.
generally an up'd rogues bow gets a 20% enhanced damage jewel with 15 max dmg. and it will stay lvl 30. or if u find a rare that's rLvl 1-25 use that.
Consider non-up'd twitch, the gains in def aren't worth the str investment, imo.
Ias Results for GA:
Rogues Only = 9 frames
Rogues + Twitch = 9 Frames
Rogues + Twitch + Bfists = 8 Frames
Rogues + Twitch + Death's/Sigon's belt+gloves = 8 Frames
so basically Twitch + bfists (and string of ears) gets you 8 frames.
charged strike + GA zon doesn't work at lvl 30 very well. you'll use LF instead.
