I’m not sure if this is a bug or a feature request:
When a character is hit with an entangle their Strength goes to zero. Then if they get a strength bonus, their strength remains zero and when the entangle wears off, their strength goes back to its original amount and the bonus is lost.
It does work that way for both entangle and web. During the time effect is on the troop original value can’t be incresed or decresed.
Here was my explanation from recently.
I understand the mechanic, I just dont like it.
