I just posted this on a different forum. The underwater environment is VERY different. It will require a re-thinking of many things we hold as SOP.
High level 2nd ed D&D. Knowing that the Koa-to live in semi-underwater lairs the party planned accordingly. The mage even brought extra Water Breathing scrolls (not sure how the papyrus would hold up under water) and the cleric cast Continual Light on different pieces of gear. All went well until they faced the Kraken.
The mage unleashed a Lightning Bolt.
Which detonated/discharged/grounded at the end of his finger, killing most of the party...
