big illusion wave

This spell is produced by the Trixter antennas. Except if the target has psychic (magic) immunity, or it see the casting and succeed an insight check (19 or greater (+1 for every added caster)), the attack will always succeed. Each target need to succeed an insight check to see through the illusion. 

This is basically an upgraded version of the medium illusion wave. It needs at least 10 caster to succeed. The spell produce an illusion of the caster that will always target all senses. It can last for 2 minutes (+30 second for each caster added to the group), or until they lose concentration (either by will, or because of a distraction). It can be any size up to 8 cubit feet and will reach any target the caster detect in a 50 ft radius. It will always cover the casters as they can't cast it on other target than themselves. It can induce status effect such as frightened, deafened or blinded depending on the illusion as long as it last. It can be cast only once per day. One of the caster can use a melee or range attack during the round.
