Hi, this cantrip is awesome, and has a very good base idea. I do recommend making a few balancing changes: rather than the strength buff giving you proficiency in all weapons, I think it would make sense to give proficiency with strictly STR based weaponry, and applying the +5 damage bonus would replace your regular strength modifier (that way they wouldn't stack).

secondly, I recommend making this cantrip require concentration for some of its effects (speed and fly in particular), this way it wouldn't be stack-able with the effects of a Longstrider  or Haste spell from the same caster.

Thirdly, if the spell has a range of touch rather than self, it could be used to support your allies. maybe allowing the paladin to cast this on his/her cleric friend so that they can fend for themselves with an increase in strength, or letting the fighter imbue a monk ally with great speed so that they may outmaneuver the guards blocking their path.

this is just a suggestion but I do genuinely love the idea! I can't wait to think of how the 'shapechanging' effect of this spell comes into play (like growing tiny wings on a creature)!

Awesome spell idea, but wayyyyy too op for a cantrip, keep up the good work :)

This is better as a first level spell.

Paladins and Rangers don't get cantrips.

As someone has already stated, Paladins and Rangers dont get cantrips. But also I would change the cantrip part. The Spell is good on paper, but way too strong for a cantrip. If it was 2nd level, I think it would be good. No hate. Really good Idea, just needs a little balancing.

great spell, gotta love the 10ft fly speed

this should probably take an action instead of a bonus action because it's a bit powerful
