With a bunch of the core features working, it's time for content, and lots of it! This patch is so large that I've likely missed a few things from combing the commit log, so let's just consider them secret extra content you can discover as you play.

Skills

• New active skill - "Shield Toss" - Throw a shield in the direction you're aiming. The shield will bounce to nearby targets, until it runs out of bounces or the next target is too far away
• New passive skill - "Thicc Shields" - Scales your Shield Toss damage multiplier by your block chance
• New passive skill - "Disc Golfer" - Increases the number of bounces your shield can do before disappearing

Temporary Skills (Skills you pick up on an individual run)

• Added a new class of luck-themed temporary skills that can occupy either the defense or offense skill slots at random
• Added a secret class of temporary skills - You'll have to figure this one out yourself
• Added Luck skill - "Greed" - Increases the gold you earn by 20% per point
• Added Luck skill - "Enlightenment" - Increases the experience you earn by 10% per level
• Added Defense skill - "Shield Wall" - Increases block percent chance by 5% per level

Gameplay

• Upgraded the rendering pipeline and lighting effects
• The Nexus has been redone to use the new pipeline. Other areas will be upgraded later
• The Shopkeeper and The Crafter are no longer unlocked by default. Explore the Forest to find them! They will disappear on existing characters due to the nature of this change, sorry! Unlocking them should be easy if you're far into the game
• The first upgrade event always offers one relevant Uber skill to help flavor your run a bit

Bug Fixes

• Using fire damage against any monster in the Treant encounter should no longer result in the encounter becoming unwinnable
• You should no longer be offered basic offense/defense skills beyond their skill cap. Unlocking them in this state did nothing but waste your level up anyways!
