im pretty sure i didnt lag at all when trying out the battle sprites but the delay makes it feel like so. lets say i press the 1st skill button, sometimes it works, sometimes nothing happened. its as if the battle sprites only attacks when it feels like attacking.
is it perhaps i cannot use the skill while walking/attacking/dashing/blocking or any sort of movement at all? i mean standing still to use the skill with a chance of it not even activating is kinda risky in tier 3. perhaps you should just get rid of the "knight-pointing-at-enemy" animation and just make the battle sprite attack :/ because at this rate the battle sprites are kinda useless.
p.s: seraphynx heart attack skill said to add increased chance for monsters to drop hearts when killed. can you be more specific? im pretty sure the chance is as low as 5% or so because i killed like 10 of monsters and none dropped while using the skill whilst when i wasnt using it at all it finally dropped. i think its fair to have the cooldown shorter than 60 seconds but gradually increasing it as the skill gets more % of chance for hearts to drop instead of making it a crappy skill with 60s cooldown :v
You can use them while walking, definitely. Do all the time. You can't while attacking/defending/dashing.
