Wildmorph is a cantrip that does the same thing as the Wildshape feature from the druid class, but better.

When casting this cantrip, the caster is able to morph themselves into any creature of Challenge Rating 3/4 the casters level, rounded up. They can stay in this form for hours equal to their level or until they wish to morph back into their original selves. The caster, once morphed takes on the stats and health of the creature they morphed into until the form is dispelled or all of its hit points have been used (can use average hit points or roll dice to determine).

Example: If the caster is level 5, they could morph into any creature with a CR of 4 or lower (3.75 rounded up to nearest whole number) and stay in that form for up to 5 hours

If the caster was level 11, they could morph into any creature with a CR of 8 or lower (8.25 rounded down to the nearest whole number) for up to 11 hours

At level 20 the caster can morph into any creature with a CR rating of 15 or lower, and stay in that form for up to 20 hours.

If the caster has equal or more druid class levels than any other class their character has all combined (an equal or greater number of levels in druid as they do their every other class when added) (i.e, level 5 - druid 3, fighter 2) then they can turn into any creature with a CR equal to their character level. (For this to work, the caster needs to be more druid than any other class. More examples include: character level 11 -  druid 6 levels, barbarian 5 levels,  Character level 12 - druid 6, barbarian 3, fighter 3,   Character level 17 - druid 9, cleric 8) Not work examples: Character level 15 - druid 7, fighter 3, rogue 5   Character level 11, druid 4, fighter 4, barbarian 3   In these cases when you combine the class levels the character has in any class besides druid, those combined number of levels is greater than the levels the character has in druid itself.
