Remember how I mentioned in my article on Hero equipment, that the Ent set is becoming popular to campaign with? That is because each piece of Ent set has two identical bonus attributes: 1% Life to ALL troops (so 2% per piece). But to be effective, do not just swap out all your gear to Ents just yet. To be most effective, use these pieces:
If your Hero has Pilfered gear, only use Ent weapon, cloak, amulet and/or ring*/**
Any sets lower than Pilfered can be freely exchanged for Ent.
*You don’t need to swap the Pilfered shield for Ent, as it deducts 2% standard life bonus for 2% bonus. See this chart.
**I don’t know whether the 5% life bonus of all 4 Ent pieces weighs up to the 5% attack loss compared to full Pilfered, but I’ve read that the Vitality score outweighs the Efficiency score in campaign, hence this set-up becoming more popular. Try at own risk 🙂
