Might as well add stuff since Ezk started the topic :P Glacors have 3 stages, and at each point are able to attack with melee (in close range), magic, range, a solid freezing attack and a special icicle attack. The magic attack is fired from the left arm, and looks like a blue-ish glowing ball. It is only partially soakable with protect/deflect magic. The melee attack is only perform at close range, and is only partially soakable with protect/deflect melee. The ranged attack is fired from the right arm, and looks like a single icicle. It is completely soakable with protect/deflect ranged. The special icicle attack shows the Glacor flinging both its arms down and launching 3 icicles at you at the same time. It targets the spot you're standing on, and if you do not move off the spot before the attack connects, it hits you for half your current LP. The solid freezing attack turns you into an ice cube, much like in the quest, and requires you to click to move elsewhere about 5 times to break free from the ice. Failure to do so within a time limit will result in the Glacor smashing the ice cube, damaging you. At long range, the Glacor will attack with one attack style for a period of time, before switching to the other style. Activating a deflect/protect prayer shortly before the attack reaches your character is enough to provide protection. After weakening the Glacor to about half HP, it summons 3 Glacytes and becomes immune to damage. You must kill these 3 Glacytes before you can damage the Glacor again. The Enduring Glacyte can only be damaged when it is far away from the Glacor. The further away it is, the more damage it takes. The Unstable Glacyte has an "LP" bar that charges over it. When this LP bar fills, it stops moving and attacking, and about 3 ticks later will let off an explosion, hitting itself for 90% of its remaining LP and damaging you with unsoakable damage if you're standing next to it. If not killed shortly after, it starts regenerating LP rapidly and prepares this explosive move again. The Sapping Glacyte drains prayer points by about 10 with each attack it makes. There are no tricks involved in killing this creature. All Glacytes only attack with melee. The Enduring Glacyte is not aggressive on summoning, so you need to attack it to draw its attention and lure it away. Once all 3 Glacytes are dead, the last glacyte killed determines what the final form of the Glacor is like. If you kill the Enduring Glacyte last, the Glacor gets a damage reduction of 60% on all hits. If you kill the Sapping Glacyte last, the Glacor drains prayer points (16~ for me) with each of its attacks. If you kill the Unstable Glacyte last, the Glacor gets its own instability - it has a second health bar which causes it to explode when it fills up, but after that, if it's not killed, it regenerates LP extremely fast. Drops received so far : 323 headless arrows, 43, 57 addy bolts (unf), rune longsword, rune plateskirt, rune battleaxe, mud runes, blood runes, nature runes, steam runes (rune quantity unsure), coins (unsure quantity), Shards of Armadyl They also drop 3 charms as a side drop. EDIT : Additional info wise, Fire spells seems to have a damage bonus against them - I'm not sure of the exact % boost but I've scored a 818 hit with Arcane Stream, Chaotic Staff and Fire Surge. Also edited post a bit.
