There are not having blood tap is a majorflaw in a summonerbuild actually in Allods Online, it may not look too special but its one of the sweet reasons we actually run low wisdom, thatswhy the route through blood tap and burning acid is very legit right now, burning acid also means volatile becomes a skill that does pretty sweet damage as it will crit quite a lot even with only a 60% boost and decent luck.

But you can get 36 rubies not 37 for them at level(Allods Gold) 42 actually. The new patch supposely fixed the old June world mystery so now they must really go depth into the game to get that rubie- unlike chapter 1 players who got the rubie at 66%. The Route Bloodgrinder showed is very good too. Blood tap is a good skill for pve or pvp not much more of use but the Increase crit rubies do help(you will find it a waste because it effects only 2 dots).

Healing shield any level is great cuz it stacks with the runes. lv 1 isnt so great but better than nothing since you will get hit and you will have no choice but to have your shield up. at level(Allods powerleveling) 3 it really shines which heals for 10k regular with lv5runes and can crit 20k per tick- pretty much neglecting the dmg you recieve in pvp and pve.
