I think it is weakness probably, it is so annoying cause you gotta use a wandstrike to get it off, and it is the most annoying when the wandstrike is your school and have blades on you and traps on the enemy/enemies.
oh my glob its always weakness I always am about to use a all enemie attack spell with lots of blades and traps to kill them and then weakness :P so after they have like 85 life or something oh and im balance so I actually have the spell myself XD
Well, since I haven't yet encountered this "weakness" thing y'all are talking about, or a lot of the more advanced spells...
Absorb Shield (Encountered this once fighting a boss way above my level. ^^ It just takes so much TIME!) Locust Swarm (Whenever I see it, I just go O_O! I dunno why, really.) Storm Shark (Lots of damage. Not lots of pips.)
If it's me fighting against a CPU opponent, the last spells I ever want to see is a balance or ice symbol being cast while the opponent is low on pips. Reason? Because there's a good chance that it'd be a Weakness or an Tower Shield. My biggest pet peeve!
As for a spell itself and not its effects ... Cyclops is a bit annoying because the flexing animation makes it much longer than most third-rank spells. It may get a bit tiresome.
I can deal with efreet's -90 and deaths virulent plague and a little weakness but I hate the mana burn with every fiber of my being it was such a pain in Avalon and Azteca the balance spammed it in az to much i hated it but then there is enfeeble I hate it but not as much as mana burn I usually use one or too blade spells
Weakness means nothing to me... Wild bolt on the other hand drives me insane especially when i just about defeat a rank 12-13 boss and then they critical blade it with a result of 2400 damage without resistance Though everyone has resistence to storm by the time you reach celestia -where its introduced-
