Spell lock?

[Derpykat5]

So I've noticed that during challenges, my non-instant spells will "lock" when active; the arrow to access the spell panel turns grey and I can't click on it or swap out the spell. Oddly this only happens during challenges, not in normal play.

Yes, that's normal and intended.

But why only in challenges?

Because removing spells before they end might cause issues in challenges and/or make them too easy.
The same thing applies for removing upgrades not being available in challenges.

It's kind of a useless mechanic for 90% of challenges. If you need to swap spells, just save then relaunch your game.

You can remove upgrades?
... why would you ever want to do that?

But I do see the point, though. Being able to cancel a spell would probably make some of the "cast x" challenges take a lot less time.

Mostly for summoning duration upgrades, you may want to remove them to cast your summons faster (for the Trial of Talent for example).
It's also useful to find some bugs and/or to test mechanics to understand them properly.

I'm sure there were many better reasons to implement it when it was implemented, but it's all that comes up to me right now.
