Alton's Lucky Streak

3-level Divination

Positive energy is expended to sway events in your favor until your focus stumbles. Whenever you make a d20 roll and receive a result of 11 or greater, you gain a cumulative +1 luck bonus to all d20 rolls for the duration of this spell. This luck bonus is added to the actual die roll, to a maximum of 20 on any one roll (so a +2 luck bonus on an attack roll of 19 would change the result to 20, inducing an automatic hit, critical hit, an increase in this spell's luck bonus, and so on). You may have a maximum luck bonus of 2.   Whenever you roll a d20 roll and receive a result of 10 or less, this spell ends. For all d20 die rolls, luck bonuses from this spell do count towards calculating whether the result is over or under 10, and if you reroll the roll (such as via a Luck feat) or change its result (such as via Alton’s Lucky Moment), only the final result counts towards this spell (so if you roll a 4 on a save and reroll it via the Lucky feat to 17, you gain a +1 luck bonus and this spell does not end).   The Lucky feat is required to cast this spell.
At higher levels: When you cast this spell using a spell slot of 4th level or higher, the maximum luck bonus increases by one for every two slot levels above 3rd.
