Let's define this category once and for all, no more questions and misconceptions, with respect to it's previous rules

I will just go by a set of rules, with which we point out the flaws and agreement

1. No damage of any kind (environmental, enemy, self, etc) - Obvious, doesn't need change.
2. Proceed through the "intended" gameplay path - We must go through the level as it is the main path with no side areas, or with them, but with a few exception, like the lava lake (skips 1-3), lukki area, (skips 5-6). I aslo need to mention the tree. Since it's not really where you need to go, and we do it for the worm egg (vision) and greed curse (a lots of money with a negative side effect).
3. No skipping levels - previously aforementioned level skips not allowed, now Holly Mountain digging, allowance or not. If allowed, where can we dig, only towards the exit (lower open entrance, or hm collapse trigger), or anywhere but not sideways, because semi-skip.
4. No wands dropped by the ghost (gold drops are ok) - Obvious.
5. No Invisibility of any kind - Obvious
6. No teleporting of any kind except the Holy Mountain portal. - Obvious, but the side puzzle or a stage puzzle like the snowy depths eye secret and hiisi base eye room contain their portals. if rule 2 is the second option, it can be allowed. If it's the first. only the eye secret from the snowy depths. Swapper mage attack is allowed and getting randomly swapped via hurting the swapper mage.
7. No Ambrosia or Glass Cannon - You can get stained or get inside the Protection From All fields from the SQ biome modifier, but not get hit while under the effect of protection from all, aka BLOCKED message is forbidden.
8. No "rare" alchemy, even if found by luck - This is the draught of midas, it's the only thing which can change a favor in your side, It's funny, because it implies the infinite money is the problem, yet, the current record held the same issue with pheromone ghosts. Shall we ban this as well? It won't affect the previous runs as it is, but the future players won't have to use the older version of the game.
9. Polymorph is allowed as long as you don't take damage during its duration - Weird one, but it's a very Noita mechanic, let's add this, you are allowed to get hit by a non-damage polymorph attack. Since it did happened before and was considered such.

Here is a thing. I think I can kill Tiny with omega sawblade, and teleport away without seeing him being killed, if I will move to a MoM location and start killing him afterward. Expo: I know what normally you would need a proof of a kill in order to confirm the said kill. Like the explosion offscreen of the mecha kolmi is enough, since being in the distance where you CAN see it, will often damage you, so we avoid the damage but will stay for the visual effect. But Tiny has an interesting mechanic bound to him, like dragon he is going to chase you down a long distanse away, but did you know what he has a teleportation? He can teleport to you if you are far away from him, like 2 screens away. If he will not teleport to you in 10 second to try and kill you, would that confirm what he is dead?

Because getting away from omega sawblade is easy if I don't watch him die from it. And obviously it saves time. I will not gonna do that for now, but would like to know what do you think. Overall if you would like to add anything to the how much is enough for the confirmed kill of all bosses, feel free to speak.
