To be fair, the spammable 5+ regen enchanted item for 20 pts in the HE army book shouldn't exist, or it at the very least it should 1) not be spammable and 2) be restricted to non-monsters in the same way as so many items and rules (like vows/gifts) where in the last FAQ.
No one should look at it as a guideline for balance. It's one of the most stupid items in the game; it's too cheap, it's spammable and it's an enchanted item instead of the more sensical talisman.
