Isair and Madae

Isair and Madae are the twin last bosses of computer game called Ice Wind Dale 2, along with his sister, Madae. They are the children of Belhifet, the original end-game boss of Ice Wind Dale 1. Belhifet has used Elven Maiden Ilmedia to plant his 'seeds', and as such, half-elven, half-fiend abominations named Isair and Madae were born.

They had quite awful memories as a child, since they were half-demons, their mother commit-suicided, and people in Kuldahar (the fictional city they were born to) tried to kill them, thinking they had murdered their own mother. The twins murdered the people to defend themselves, and escaped. Only to build Legion of the Chimeria, the army consisting of abominations and other hated races, such as goblinoids, and demon like things. They tried to conquer the Frozen North and Ice Wind Dale region. The game IWD 2 allows players to play the heroes to stop them.

At the last final battle, players will face Isair and Madae in their fortress, Severed Hand, an encient and abandoned elven fortress, which was also in the first game. This fight is particularly difficult due to sheer amount of tough enemies and Isair and Madae's brute force.

Isair is a twisted sorcerer/rogue. He dual-wields two nasty scimitars which poison/stun/disease the victims. His most used strategy is going Improved Invisible, and making sneak attacks. Sneak attacks are extremely damaging and deadly, he also likes to create Black Blades of Disasters to disintegrate players.

Madae is a priestess of Xvim, the bastard son of Bane, and she also has some fighter levels. She uses dangerous disabling spells such as Blasphemy, which stuns all good aligned players, and then goes with Mass Dominate, which is extra hard to resist and simply, so devastating to end the battle instantly. She then summons very tough monsters, demons, and uses deadly Harm spell, which instantly drops a target to 1 HP. She also can attack with her club which also does good acid damage.

They are also all buffed up to the max with spells before the battle, and since they are half-fiend they all have good natural resistance to most anything. Spells, damage types, etc.
