my haunted spider is only level 5, so i only use it in a pinch. my go to lineup (for high mana matches) is ha'on, pegasus, phantom soldier, soulstorm, elvin mystic, and octopider with contessa as the summoner. -2 range, -2 magic, and -1 melee. everything funnels through the ha'on because of taunt and the blind from octopider and his flying ability give me some misses and he also has reflect so those weakened magic attacks get sent back.
