My question is why do you not just give the character 2 shields?
There’s no limit on shields is there, or may there may some benefit to not giving the character an additional shield?
Thanks in advance
A character can have a maximum of 3 shields.
It's not that easy to find but it's in the Rules Ref. guide p.9
Dice symbols - Shield
••A character cannot have more than 3 shields. Any excess
shields that would be given to the character are ignored
