The 2nd edition of Yoon-Suin will soon be upon us. Flee in terror before its 12 adventure sites, many extra appendices, plethora of random encounter tables (finally!), new maps (by Tom Fitzgerland) and entirely revamped art (by Matt Adams), and its new monsters, like this one:
A race of humanoids with spongy green, yellow, black or red flesh and the ability to propagate explosively. They are unintelligent, uncultured, and uninterested in anything except eating and birthing; left to their own devices, they will impoverish vast regions with their insatiable appetites.
HD 1-1, AC 8, #ATT 1, DMG 1d6 (bite), Move 120, ML 7, Save as F1, TT None
*Green aphid-men can squirt sticky sap at a single attacker within 12', hitting automatically and slowing it for 2d6 rounds; yellow aphid-men produce a foul-smelling oil on their skin which stings the eyes, meaning melee attackers suffer a -2 penalty to ‘to hit’ rolls; black aphid-men can suicidally explode, spraying a noxious fluid over an area 6’ in diameter identical to a stinking cloud; red aphid-men excrete a waxy fluff on their skin which permanently coats non-magical hand weapons and renders them blunt and unusable on a successful hit (though that hit still does damage).
Usually encountered in groups of 20-200. One female can produce a precise copy of herself at any given moment, once a month; that copy is born pregnant with another copy inside her, which can be birthed after a week.
