Level 16:
Escape Plan: Mounting is instant and grants 60% Movement Speed that decays over 3 seconds before you become dismounted. Mounting has a 8 second cooldown.
Debt Plan: Every 30 seconds, 25 Moola will spawn near Felix.
Medical Plan: Healing Spray will no longer affect enemies.
Battle Plan: Activating Payday! will reduce the current cooldown of all basic abilities by 3 seconds.

Level 20:
How to Control Your Oaf: Chemical Rage now increases movement speed by 25% for the duration, and Felix is no longer silenced.
Cha-Ching!: Targeting a enemy hero with Transmutation Potion will now turn them into a statue of solid gold, stunning them for 3 seconds. Enemy heroes stunned by Transmutation Potion now take 25% increased damage from all sources. Increase the cooldown of Transmutation Potion by 20 seconds.
Oaf-erational Procedures: When Helix's health drops to 0 he will leap to a nearby allied hero and ride their back for 5 seconds. During this duration Helix will be able to cast untalented versions of Acidic Firebomb and Healing Spray. Once both spells have been cast or the duration is up, he will hop to another allied hero and repeat this. He may repeat this until he respawns or until there are no nearby allied heroes to jump to. If there are no nearby allied heroes, he will disappear to await his respawn.
