Constructs a lightning spire in a nearby location. It can fire bouncing bolts of electricity at the caster's foes, but is completely immobile. The strength of the spire depends on spell power.

Summon Lightning Spire is a level 4 Summoning/Air spell which summons a lightning spire.

Effect

An immobile lightning spire that shoots bolts of electricity will be placed on a random location, within a two square radius of the caster. The location must be empty, and not deep water or lava.

The Hit dice of the lightning spire are <power> / 10 (but at least 1).

Higher spell power makes the spire more powerful.

The construct lasts for around 18 turns, regardless of the spell power.

Strategy

• If you roll a good spot, lightning spire can hit doublezaps on monsters when its bolt reflects off a wall.
• The spire will avoid shooting allies, including you, unless they are electricity resistant or invisible. So make sure to position yourself and your allies in a way that allows the spire to remain effective.
• The lightning spire cannot see invisible. If you or one of your allies in its line of fire is invisible, it will fire its bolts right through you.
• You can use the spire to block line of fire for hostile hexers or to seal off a corridor when you need to retreat.
• The spire is immune to electricity, poison, and negative energy, so you can safely shoot bolts of lightning, venom, and draining through it.

History

• This spell was added in 0.14.
• 0.25 made the placement random and changed the spell schools from Air/Summoning to Summoning/Air.
