The armorist level 20 ability:
Infinite Arsenal (Su)
At level 20, you no longer need to spend a spell point to summon equipment.
But on the blaster archetype, summon equipment is replaced:
This replaces the summon equipment class feature.
However, blaster does not replace IA. I thought the capstone was affecting bound equipment, but bound equipment does not cost a SP to summon from lv 1 anyway.
Table: The Armorist
1st [...] Bound equipment, casting, spell pool, summon equipment [...]
[...] Bound equipment is summoned and treated just like summoned equipment, except it does not cost a spell point to summon [...]
Am I missing something obvious on the archetype, or the lv 20 ability is really useless?
