When crippled and free running you run as fast as they do. To run any faster, you want to have that ring of haste. When enemies move as fast as you, you can do a half circle around a 1 block obstacle (like grass) and they will lose track of you. Glyph of flow or haste also help, as will ethereal chains or timekeepers hourglass. Or just stealth, which gives you the bonus move speed even if not free running, just level the appropriate ability. Plus, free running stacks with haste or stamina potions, so use that to your advantage.

They only have to change their name if it's trademarked, which Pixel Dungeon isn't.

Whenever I play duelist I find myself going champion just so I can always use a daggers ability. I'll be fighting yog with a t2 dagger in my offhand just for the ability lol

The idea behind freerunner is that you run from fight to fight with enough time in between each encounter for your ability to recharge, so you pretty much always move at 2x speed with bonus evasion in combat. I would recommend focusing on throwables only if you have a ring of sharpshooting or upgraded boomerangs, as that makes you a menace at range. For this, you play similarly to a sniper build, with tele grab. Rings of haste and evasion also work nicely with freerunner. Tbh freerunner isn't as good as assassin unless you already have the rings I mentioned above or a ranged build with a crossbow or something, so you have items that synergise with your ability.

With warlock+RoW I don't think there is a limit to how many you can get, that could be a fun challenge

Tengus interaction with charm is weird. He stops throwing shurikens at you, but will still use other abilities as normal (cause they aren't direct attacks, I guess?). This makes affection very helpful for the first phase and not as helpful for the second.

I would get to an alchemy pot to see what trinkets I get. Then imbue your staff with one of the wands you have and use at least 4 SoU on it. What wand you imbue is dependant on your play style/trinket. If you have 14str I would just try on the chainmail and hope it isn't cursed, it might be upgraded which would help. With a decent staff, 2 heal pots, and 2 blink stones from that teleport scroll, you should be able to kill tengu.

Someone clearly hasn't read the effect description of 'focused'. It is pretty clear that it will block an attack even if the attack is otherwise guaranteed to hit, which includes surprise attacks and duelist abilities.

The rogue has a t3 ability that allows him to use his cloak even when it is unequipped, at the cost of a slower recharge time. Fully upgraded this reduces the charge speed of the cloak by only 25%, and otherwise the cloak maintains full functionality. What you are asking for is literally in the game, you just need to beat tengu.

With bandits, which also pathfind away from you, they have a slightly reduced movement speed so that you can catch up every 6 turns or so. I feel something similar should be implemented with the trickster. It would preserve the challenge of the boss and its core mechanics, but make it beatable without requiring specific items to counter.

Further evidence that ethereal chains are the best.

Yeah, this game is really just a learning curve. Took me 80+ runs to get a w, and now without challenges I win about 30% of the time. I've been struggling to get a win with 6 challenges though.
