Shattered Pixel Dungeon is an open-source traditional roguelike dungeon crawler with randomized levels and enemies, and hundreds of items to collect and use. It's based on the source code of Pixel Dungeon, by Watabou.
Cloak of Shadows expends a charge on activation but there seems to be an exception: not during a time freeze. I don't think activating the cloak during a time freeze even costs a turn as it normally does. Activating Timekeeper's Hourglass & then the cloak only spends a single hourglass charge. Deactivating the cloak doesn't cost any time or charge, as usual. I didn't test this w/ swiftthistle but I imagine it's the same.
This allows for a freerunner exploit where you use hourglass charges instead of cloak charges to build momentum when using the Speedy Stealth talent:
1) Activate Timekeeper's Hourglass.
2) Activate Cloak of Shadows.
3) Run around until achieving desired momentum lvl.
4) Deactivate hourglass & cloak, in either order.
Cloak & Speedy Stealth allow the freerunner to take 2 steps for every 1 uncloaked. Ring of haste +3 can make that 4:1. This combo allows for building 8 stacks of momentum off 2 hourglass charges & 0 cloak charges in an instant. Even better w/ flow or swiftness glyph on the armor. It's always strictly better to move cloaked when using Speedy Stealth during a time freeze because it doesn't cost the cloak anything.
Prob not as exploitable for assassin but I think you could build a lethal strike in 1 turn w/ Enhanced Lethality.
