Hmmm, well I assume that the four new items that were already coming with the Endless Mode update will be the equivalents of the Adrenaline, Burner Phone, Bad Medicine, and Inverter from Buckshot, so thinking of new possible mechanics took a little bit but I can toss some concepts and themes/items that I'm personally quite partial to:
- Pocketwatch/hypnogoggles (not sure what they could do though besides basically being a second variant of the rope item by stunning the target in a trance where they can't help but masturbate)
- Chastity belt (perhaps it blocks the next instance of damage? maybe also makes it that using a vibrator egg will deal damage until it breaks on the next normal hit, or makes that next hit deal extra damage?)
- TENTACLES!~ (prevents you from using items until you next play a card by "distracting" and "playing" with you?)
- Demon-Nip™ or a pentagram/summoning circle (summons a bunch of imps/demons to gangbang both the target and user, dealing 1 damage to both)
Other than that I mostly have outfit ideas inspired by a comment on the main game page suggesting them: catsuits, shibari, living slime clothes, etc. each with different little "perks" lol. But that's beyond the scope of this question, and would be a lot of extra work I assume, so we'll just leave it at my item suggestions for now, since they're already a lot to consider lmao
