This run:

Cleaned up some boss fights with new strats, learned the sword swap glitch and used it to get through Magridd Basement much faster and safer. Made some routing errors and forgot some stuff but still managed to cut some time off my last run. Still tough battles with Demon Bird but the Deathtoll fight was much smoother this time. Saved about 19 minutes on this run. I can probably still shave off another 15 to 20 minutes with more optimized grind to level 13 and less deaths to Demon Bird.

Premise:

The low % run contains the challenge to complete the game with as few items/equipment as possible. I had initially wanted to find a way to bypass the Bubble Armor and use Herbs to refill my health in Act 3 for going through the underwater area's. This eventually led to the thoughts of attempting to yet remove another item, the Herb. By increasing your level, you gain 2 HP per level, and I figured out it would take level 13 to be able to make the runs through the water without Bubble Armor. This led to where we are today.

This run follows the Any % route but does not pick up any helpful upgrades and gets through the game with the absolute minimum items and equipment. This makes combat a challenge since you can only survive a few hits and new boss tactics needed to be created. Act 3 is the most changed route as you need to spend time grinding experience in Southerta to get to level 13 before you can make any dives to the other islands.
