Bestow boon

When you cast this spell, choose the nature of the boon from the following options:

• Choose one ability score. While blessed the target has advantage on ability checks and saving throws made with that ability score.
• While blessed , the target has advantage on their first attack roll.
• While blessed , spells and other magical effects can neither reduce the target's speed nor cause the target to be paralyzed or restrained.
• While the target is blessed , their attacks and spells deal an extra 1d4 radiant damage.
• If the target would drop to 0 hit points as a result of taking damage, the target instead drops to 1 hit point and the boon ends, For every 2 levels this is upcast, gain an additional use of this boon.
• If the target has at lest 1 hit point they regain their con modifier in hit points at the start of their turn, up too half their max hit points.

At the DM's option, you may choose an alternative boon effect, but it should be no more powerful than those described above. The DM has final say on such a effect.
