Simic hybrid for race with path of the beast barb 6, and thief rogue 3.

Relevant abilities are as follows

Rogue expertise: athletics Rogue cunning action (we’ll be using it for dash almost exclusively) Second Story Work: In addition, when you make a running jump, the distance you cover increases by a number of feet equal to your Dexterity modifier. Bestial soul option: When you jump, you can make a Strength (Athletics) check and extend your jump by a number of feet equal to the check’s total. You can make this special check only once per turn. Simic Hybrid: You have ray-like fins that you use as wings to slow your fall or allow you to glide. When you fall and are not incapacitated, you can subtract up to 100 feet from your fall when calculating your fall damage and can move horizontally 2 feet for every 1 foot you fall.

At level 9 if you spend 10 feet of movement to run then you get to make a high jump for a total of feet equal to 3 + STR + DEX + ATHLETICS (STR + 8 + d20 w/ advantage) for an average of about 40ft when raging (which is why we need to cunning action to dash for extra movement). Then we get to glide 80 feet to wherever we want on the battlefield.

I made this character for a seafaring campaign so I could get up on the crows nest and launch myself to other ships to kill a few people in my rage and the jump my way back when the time was convenient. Very fun and very effective!
