Consignment
Ioun Stone Emerald Prism - 2011 (Platinum) - C17
Note: This is a Consignment Token (hence the C17), which means a True Dungeon adventurer is selling it through Trent Tokens. But as with all Trent Tokens products, once you've made your purchase, you'll receive a tracking number and your token will be promptly mailed to you!
Allows the use of slashing, blunt, ranged, or thrown weapons while underwater. It does not remove the Hindered penalty.
Hindered: When underwater, creatures not native to water (including player characters) are very slow to propel themselves. In melee combat, only characters wearing Boots of Free Action (or a similar magical effect) may attack the first round. In addition, without magical aid anything requiring movement or a Move Action is not possible during the first round of combat.
Text On Token: Removes all underwater weapon use restrictions
