Snake ring and touch attacks

[Tolkien]

The snake ring gives the wielder the item spell "poison touch", it doesn't actually give the wielder an extra attack.

[Redeyes]

There are some items that add extra attacks and stack, from what I recall that they (besides direct weapons) are the chi shoes, dancing trident, astral serpent, stone bird, and the horned helmet.

If you have the quickness buff/heroic quickness the additionl items will also strike another time.
