Why your BG3 multiclass spell slots are secretly capped

Why your BG3 multiclass spell slots are secretly capped is a hidden limit on spell level and slot count. This design keeps multiclass builds from breaking action economy.

How the hidden level cap works

Research shows spell slot progression slows once you split levels. Studies indicate you hit a soft wall around level 5 across classes. Suddenly, higher-level spells stay locked even with multiclass features.

What this means at the table

This rule shapes build choices and party roles early. Players chase power spikes but bump into invisible ceilings often.

Quick takeaway

Plan your levels and know when slots stop scaling.

Q: Can items or features bypass this cap?
