This creature appears as a green humanoid with coarse, rough features.
Its appearance is misleading, however — it is in fact a colony of algae which, assembled in this form, has developed some mobility and a rudimentary intelligence. Its form is only of a temporary nature.
It attacks otherwise with its powerful fists each of which can inflict 1-10 hit points of damage.
It is immune to psionic attacks but can deliver one mind blast per day.
The algoid has control over certain types of trees, similar to the control exerted over trees by the treant. The types of tree over which the algoid has control are those which will be found near its normal habitat (swamp, lakeside pasture—at all events close to water of some kind whether stagnant or otherwise); thus it will be able to control two willows, water-oaks, cypresses or other similar varieties of tree. Trees thus controlled move at 3" rate and strike with two attacks per round for 1-10 hit points of damage each.
Edged weapons will pass through an algoid without doing any damage, unless they have a magical bonus of +2 or better in which case they inflict half normal damage. Blunt weapons—magical or otherwise—will do full damage.
Despite their immunity to certain forms of magical attack (fireball, lightning) algoids are particularly vulnerable to part water and lower water spells, each of which inflict 1-6 hit points of damage per experience level of the spell caster.
