Mesmer duelist's discipline
Phantasmal duelist summon range has a base value of 1200, like all phantasms. This does not change, and has never changed. What I have not tested is whether it affects the range that the actual phantasms can fire at. You may want to look into that.
Trait says it increases illusionist pistol range, but it only increases mesmer pistol range. i find this annoying in W vs W when I stun an enemy in place from a wall, then cast a duelist illusion only to have it fail due to range.
