Real simple suggestion. Can you toggle Ushbati to STOP collecting souls you have? As someone actively going for 200M slayer, be much easier than having to keep banking/withdrawing it for specific tasks when it draws from a pre-set.
A lot of people run pre-sets for Slayer. Having to continually bank or check is just a time waste. Not to mention if you do take it, you just waste the jar.
It's a really simple implementation and I really cannot see a downside to it.
im currently 140m xp over 200m xp in slayer. im on 3.2k slay tasks. im aware how slayer presets work. just bank the the ushabtis or dont have them in preset and only bring on a task you need
still getting souls after already obtaining one is useful one for extra xp. and 2 to fill your dungeon. so if there is a toggle someone can forget its off and camp x monster for x amount of time for more souls for either xp or till fill dg. and waste time till they realise = downside
but even if there was no downside doesnt mean it should happen
especially when you could just not bring them on the task. you can also empty the ushabti if you forget to do this, therefore the ushabti isnt wasted at all
