This was previously the intended function (and was stated in the text of the spell). It has now been changed so that the maximum is equal to your level in the spell.
Everything seems super squashed together, though that may be my browser being weird. It's not just this, it's also Realm Grinder, which isn't your problem but I'll probably mention it there, too. Parts of the interface are on top of and obscuring other parts.
Needs to actually give the quests it's mentioning, items need to be more transparent, and generally needs bugfixing and more content. That said, what's here is good and I look forward to it once it's more complete!
Really sorry that happened :( just uploaded a new version and it should be fixed now
