Can two (or more) heroes support the same set of units in a battle? Everything I can find about heroes supporting units only mention one hero supporting and make it 'seem' like only one can support each type of unit.

I don't have rulebook with me at the moment, but Iam almost 100% sure that any number of heroes can support any set of units, this is how we used to play all the time.

Each hero has to support a different type of unit. (Page 25: "take any number of his heroes... and place each of them adjacent to a different type of friendly unit."

So you can't have 3 heroes supporting your Frost Wyrm, for example. But you could have them support your Necromancers, Dark Knights, and Frost Wyrms, one each.

How to calculate strenght when hero is in battle and the round 5 is ended .. does i need to calculate heros strenght or just ad 1 strenght per standing hero ?

Heroes do not provide strength in battle when supporting, they just let you draw an extra card for a particular unit type.

(There is a card that lets the heroes provide strength, if I recall; I'd have to look).

Tnx.

u mean have a tactic card ?

I would be a tactics card, yes. I don't recall if said card exists.

It is indeed a Tactics Card, from the expansion. It's called "Impressive Leadership", and gives you +1 strength for each standing hero you have in the area of the battle.
