For each Hit Dice it gains, an ihagnim grows roughly a foot in diameter and its Intelligence score increases by +1, up to a 16 feet diameter and Intelligence 16 at its maximum size of 16 HD. This intelligence increase replaces the normal ability advancement from gaining Hit Dice, but otherwise the ihagnim gains the usual improvements in hit points, base attack bonus, saves, feats and skill points for Hit Dice improvent. When their intelligence modifier increases the ihagnim recalculates its skill points and invests any surplus. Ihagnim are proficient in Hide, Move Silently and Survival as well as Knowledge (the planes) and Spot. An ihagnim has a flight speed of 10 feet per point of Intelligence on the Astral Plane, as per the standard rules for astral movement. In addition to the above improvements, an ihagnim's tentacles grow longer as it grows, gaining a reach of 20 feet at 10–12 HD, 25 feet at 13–14 HD HD and 30 feet at 15–16 HD. While writing the above I realized that we should probably rejig the ihagnim's flight speed.The original monster entry refers to a Dragon Magazine #67 Astral Plane article for movement and combat rules. That article was the basis for the standard AD&D Astral Plane rules.In AD&D, an astral creature flies at 1" per point of intelligence; so a base ihagnim has MOVE: 8″, which is slightly slower than the 9" of a moderately encumbered human.However, in 3E that changed to astral creature flying at 10 ft. per point of intelligence; so the base ihagnim should have fly 80 ft. (perfect).So I reckon we'd better increase the ihagnim's speed to match the 3E standard of 80 ft. (perfect) rather than give it 20 ft. (perfect) to match the original monster.</blockquote>
