Q: The interview with Multiplayer. It raised some questions with regard to the changes you're making compared to the core ruleset. For example, can you clarify the tweaks applied to multiclassing caster classes? Some fans are worried they might lead to overpowered characters unless martial classes are also allowed to stack extra attacks when multiclassing.

A: When multiclassing, the levels of your classes and subclasses that normally have access to spell slots are added together in a weighted formula, and then the overall spellcasting level is used to determine how many and which levels of spell slots you will receive.

Warlocks are an exception here in that they only get their fixed-level spell slots.

Someone asked about multiclassing, and... near as I can tell got told 'we're doing spell slots like 5e', but no talk about the Italian interview or how that's going to factor?
