Chessmaster quest has Bell Shell, which heals you for ~18% of the damage you do despite the tooltip saying 13.5% and halves earth damage taken. No downside. It has an earth buff SPell that gives you MRM and reduces the earth damage you take. Non-QC, so only situationally useful, but I can see it coming in handy. It also has a water paralyze MP spell for those who like status spells.
Edit: The SPell's effects scale with Endurance. The buffs are always 3 turns, but the boost to MRM and reduction to Earth damage increase with higher END. Personally I might not use it but I'm still glad to see more END-based stuff come out, it's a neat conceptual niche.
Edit 2: With 0 END I got ~12 MRM and x76% earth damage, 50 END got +16 and x67%, LUPUL had 200 END and got 25.7 MRM and x48.43% earth damage. The Bell Shell misc doesn't give any stats, just the healing and multiplicative resistance.
Edit 3: For fun, some people on the Discord and I started figuring out just how far it'd be possible to go with reducing damage. Stone Golem Form has 39% earth resistance, a FD lean, and -(5/1.4)% damage taken. Macka-Lot Buckler has -26% earth resistance, and up to -(10/1.4)% damage taken. The subtractive earth misc of your choice can give another -10% earth resistance. Gas Rat Grenades are a wind weapon that can inflict a choke for up to -40% of the enemy's damage. And of course the terrapin shell spell has *.48 earth eleshield. So under ideal conditions (over 200 CHA for the shield's passive and 200 END for the buff spell plus a bunch of specific items), we have a fully defensive lean for *.8 damage taken in general, 3% earth resistance, an eleshield for *.48 earth damage taken, and -(15/1.4)% damage taken in general, plus a -40% choke on the enemy. That gives us 0.56777% earth damage taken. Yes, that's an effective earth resistance of under 1%. And no, it's not possible to get that under 0%, since the only thing that could do it is a much larger subtractive boost to earth resistance. Thanks to Anim for reminding me that Stone Golem Form had an additional damage reduction effect and Flawfish for reminding me of Gas Rat Grenades.
Math: 100*.8*.03*.48*(1-((15/1.4)+.4)) = 0.567771429. We start with 100 for 100% of the damage taken, multiply it by 0.8 to take a FD lean into account, multiply it by .03 to take our 3% earth resistance into account, then multiply it by .48 to take the terrapin spell's eleshield into account. The bit after that takes the damage reduction effects from Stone Golem Form and Macka-Lot Buckler into account, plus the monster's Choke status. The first two, taken together, provide -(15/1.4)% damage, and the choke is -40% damage. They're converted into decimals and subtracted from 1 before they're multiplied with the rest to account for them being subtractive penalties to damage.
