Anti-Luck Blade Longsword

You gain a +1 bonus to attack and damage rolls made with this magic weapon. While the sword is on your person, you also gain a +1 bonus to saving throws.

Luck. If the sword is on your person, you can call on its luck (no action required) to reroll one attack roll, ability check, or saving throw you dislike. You must use the second roll. This property can't be used again until the next dawn, but the consequence is that the GM has to give you 2 disadvantages each time you use it, the disadvantages have to be given within 5 sessions, otherwise all enemy's get advantage against you for 8 hours; e.g. if you have 4 disadvantages each group of 2 gotten in one session after the other,  your GM uses 2 disadvantages, since your lowest time would then have been 4 sessions, it's now 5 sessions for the other 2. (1 disadvantage doesn't count as a half session)

Wish. The sword has 1d4 – 1 charges. While holding it, you can use an action to expend 1 charges and cast the Wish spell from it, act as if the wish was given to the player by a demon (make the spell backfire as much as possible). This property can't be used again until the next dawn. The sword loses this property if it has no charges.

Blood Infusion. If the user drips their blood onto the blade as an action (can be used twice per short rest and does 2 damage per time) it will do 1d8 slashing damage + 2d8 Poison Damage.
