-Break skill does not work. It graphically applies the debuff on targeted enemy, it is shown when inspecting said enemy in tactical screen, but it's effect is not applied, target retains full defense (against all attackers, including the Assassin who used Break).
This needs to be fixed because is one of the reasons an Assassin sovereign or champion would work, since all undead and many boss / champion type of creatures are immune to critical hits (which negates a whole line of specialization). Being able to remove one enemy defense (has a 5 turn cooldown) is what makes them viable past mid-game. This is most especially vital to Kingdom players who don't have easy access to Death spells to remove the defense of enemies.
Also another execution glitch with Rain of Arrows from Assassin path, sometimes (often) instead of firing instantly the caster remains stuck for 10-15 seconds with no casting animation then the damage happens instantly.
And finally archery bug. If my Assassin uses bows, and I researched end of the line longbows (including magical ones) who supposedly ignore 50% of target defense, that coupled with my 75% target defense ignore from Assassin path, should give me 100% Defense ignore on enemies. Yet the damage displayed on tooltip and actual damage dealt in combat reflects that neither are applied at all. With a Sovereign with 24 attack, with a bow that deals fire damage and amulets that add fire and ice damage (2 each), with 75% + 50% Defense ignore, with Break used, should do more than 1-5 damage on a Statue Lord (or what he's called, the ones leading the golem bands in scrapyard).
This is a serious detriment / handicap to ever making currently Assassin's be it melee or ranged ones. If you are forced to pick / learn spells and specialize in those because your attacks deal pathetic damage, that's a problem Houston!
