Very good.
Could be better if these changes were made:
---Before using the 'power surge' ability, the script should recognize the player's pray points, and if its below 30 or 40, then pot up to max pray points.
(( This is because the bot is very slow to switch tabs and drink potions. So to do this, it wastes xp where it could be spamming a special ability.))
--Spam click (within reason, a normal user would normally spam click) the special ability bar during the 'powerup' ability.
I notice that when playing by hand, if you spam the special bar, it will be able to use it MUCH FASTER than the bar is physically able to fill up with green. This means that you can spam click, even if you don't see a full green 50% bar or whatever. Lots more xp.
--After killing a monster, click on another to kill immediately. I know it isn't much, but these few ticks that are wasted by waiting for auto retaliate are xp wastes.
