Good Job on the spells, can't say i remember much from Warcraft 1 (to young). If you keep going with this idea maybe you could make some kinda Mod that turns War3 into War1.
Human Cleric: - healing almost the same as the WK2 healing ability, except it's a bit more effective. This is the spell what i'll probably upgrade to be more similar to WK1 or 2 - far seeing no comment (just it doesn't reveal invisible units) - invisibility invisibility hasn't changed since then except the duration
Human Conjurer: - summon scorpions summons up to 4 scorpions, each for 25 mana. If the conjurer has 100 mana, he summons all the 4 scorpions, and loses all mana. If he has 50 mana, he summons only two scorps. - rain of fire similar to the WK2 blizzard, it needs 25 mana for a single use, but can be channeled, what drains more mana, but makes the spell last longer. (there's a bug if you interrupt the channeling the conjurer will cast a new RoF to the middle of the map) - summon water elemental no comment (except all the summoneds have mana, what is draining over time, and when they lose all the mana, their health begins decreasing - like in WK1 or 2)
Orc Necrolyte: - raise dead raises up to 3 skeletons, if the necrolyte has enough mana - dark vision same as far seeing - unholy armor same as in WK2, makes the unit invulnerable but drains the half of its hp. Unholy armor cannot kill units. Unfortunately the trigger i made to do not turn the enemy units invulnerable too didn't worked, so i deleted it, and now it works the same way as in WK2.
Orc Warlock: - summon spieders same as summon scorpions, but it summons up to 4 spieders. - cloud of poison it is something like the Psi Storm in SC, except it moves in a random direction. Everyone is damaged beneath the cloud, and it disappears after 15 seconds. - summon demon no comment
That's all the spells the WK1 had, plus there are some combat features what makes the game work as the WK1 did.
uhhhhhh....what spells are they cuz im confused because i wont dl it if i dont know what it does tell us what spells cuz i never played warcraft 1 just 2 and 3
