What can I do with Challenge tokens?

[gloopygloop]

I get 5 Challenge tokens every day. I own the Challenge pack. What useful things can I do with the Challenge tokens?

I'd be happy to use the tokens to buy a minute of time or beef up my kobolds or something, but there doesn't seem to be an option to trade tokens for those things. I haven't found anything that's actually useful to do with my Challenge token.

Anyone have any suggestions? Is there a compiled list anywhere? Should I just stop taking the tokens and recover the backpack space?

If you own the pack, throw them away ;)

btw, the 5% xp pots you get for 150 mats... well lets just say you should test them cuz they are not 5% :D:D
typical turbine though

In a challenge, you can put them in a machine for a random bonus (power-up, or crest).

I just throw them away, unless I'm planning on doing that challenge that day.

Depends of the quest, on rushmore it gives 1-2 extra crests that may come handy while you collect the ones in the quest.

But the 1 minute buffs are horribly wasted, since the vaults are nowhere near the action.

On occasion you may indeed get a free universal crest or a minute of time but as with all things grind it is probably not enough for the waste of inventory space.

Yeah I haven't been taking them anymore.

In retrospect I might start keeping The Disruptor / Shortcuts ones for when things get hairy near the end with a billion red names. Crossing my fingers and hoping for a quad damage from one of the 3 vaults on the ship in the middle would be cool at that time.

Mansion pfft. Lava Caves pfft. Extraplanar Palace pfft. But maybe the kobold island ones since you have the central concentration of vaults. Just a thought anyway.

I'm still saving up found Turret Requisitions (3/5 atm) for an attempt at a decent number of stars on the disruptor; should add tokens to make it a mega-attempt.
