Features
-
[]Climb as high as you can. No Act / Floor limit![/]
[]Progressive map difficulty: The higher you climb, the harder the map becomes. Fewer Merchant and Camp sites trickle down to none. Events turn into monsters. Monsters to Elites and then Elites to Bosses. Get high enough and you will encounter multi-boss floors.[/]
[]Random and cross-biome boss pools, combined boss fights, late boss Str/Dex scaling[/]
[]Coin purse gold cap in Act 4+ at 500 gold (retains gold over when first imposed)[/]
[]When the Merchant and Camp sites disappear, a legend service appears to pay for a visit, along with the ability to expand your Coin Purse capacity.[/]
[]No duplicate relics! When a relic reward appears that you already have, a new reward appears: +Max HP, +STR or DEX, +Coin purse, Upgrade Random Card, +Gold, Heal some health.[/]
[]The climb does not technically end when you meet the Architect. Share your score and challenge your friends through shareable scorecards and leaderboards.[/]
[]Optional Infinite Ascent: Mutations add-on: after Act 4+ act bosses, the Spire rewrites your mutations (requires Mutations). Enable Infinite Ascent and Infinite Ascent: Mutations. Do not also enable the standalone Mutations modifier.[/]
Introduction
Something changed when The Architect returned. The Spire had always bent to his will, but this time the halls felt deeper. Corridors that should have ended at the third ascent simply kept going...
We now call it the Infinite Ascent. No hero has made it back to report how deep it goes.
Infinite Ascent adds an Infinite Ascent Custom Run modifier. Clear Acts 1-3 as usual, then keep climbing through new random biomes instead of ending the run at The Architect.
