I am playing my first character in Skyrim and I decided that I want to focus on conjuration. Up to now I used swords for close combat situations and transitioning into a bound sword seems to be a good choice. I looked up the damage a bound sword can inflict and it seems like that even the mythic version cannot do more than 14 damage per hit. My current sword already has a damage value of 35, more than double of the bound mystic sword. In addition I lose the possibility to enchant the sword or improve it through smithing.
On the upside I can use the perk to automatically cast soul trap which I really like. I can also use the bound sword to improve my conjuration skill. I don't use any skill boost tricks, so I need to level up conjuration naturally and the bound sword comes in handy for that.
Are those upsides enough to invest into the use of bound weapons? The lack of damage seems to be a real issue.
