Symbiosis with nymphs. Auto-translated

Guys, I was reading posts about Elves and found something interesting... Is it true that Nymphs heal Ents? I knew they heal themselves by being near them, but not the other way around... If so, how do you calculate how much health they heal? If it's just a myth (too bad!), then tell me how many Nymphs will be resurrected if you use Symbiosis. Please don't just point me to the manual; what's the point of a forum if not for that!

Well, firstly, what's the point of a manual then? Everything is clearly and understandably written there: This creature can heal and resurrect Ents once per battle and receive the same healing from them (an activated ability). A group of Ents receives 4 health points for each Nymph, and a group of Nymphs receives 20 health points for each Ent. Just in case: any Ents can be used for resurrection.

Thanks, I didn't know!
