In RL nuns (and monks) make vows. Like vows of poverty and celibacy for
example.
Why not make our nuns also take vows.
With Vow of poverty nun cant have any amount of money in bank and not more
than 1k in inv.
And that vow would also include that nuns cant wear any eq unless its a relic.
Of course, its possible that nuns could make some clothes for themselves with
their sewing skill
But mostly, the mud vow of celibacy would ban mudsex for nuns. For every
mudsex session they lose align permanently.
