Maximum amount of condition damage ?
500 isn’t a lot, no. 30 points into trickery = 300. Lv80 exotic top = 101 or something similar. Add the rest of the set and runes… I have no idea how high you can go, but it’s somewhere around 1k probably.
Don’t buy into speccing full condition damage. The only build that is useful for is P/D. If you spec condition for D/D because of Death Blossom then all that does is make 1 of your skills strong(ish) but the other 4 weak. 500 is good enough.
its not that meaningful to post a number without also posting your character level.
For example, in sPvP my Thief can equip and spec to have over 1200 condition damage.
the 500 you have might be alot if your character is level 60 or something, for example. but its certainly not alot for an exotics equipped level 80 character.
