Maybe this is not important and you might have already known, but it's very likely that the displayed range ingame is either edge-to-edge range (distance from the edge of target's hitbox to edge of player's hitbox) or edge-to-center (distance from the edge of target's hitbox to player's center) range, and is rounded up. And the target circles of the mobs/minibosses/bosses are estimated visual of their hitboxes. A few examples (I tried to stay at the furthest edge of the 1m range aka the spot where tiny movement outward would make the displayed range value increases to 2m): Had to stay at 2m range in Venena room because going to 1m will trigger all enemies Also, with that as base: - Clarity Rose, Scarlet Sakura Fairy Sword, Black Shadow Nodachi,... that were thought to have 3m range, actually has 2.5m range. - Most knuckles have 1.5m range instead of 2m. - Most halberds have 3.5m range instead of 4m. Yeah, the .5 in range exists. Idk about any smaller decimal but at least .5 exists. Using what I said above (displayed range value is edge range rounded up) to prove it. The weapons I listed, when standing at the furthest edge of their thought-to-be range (aka the rounded 3m/2m/4m), you still won't attack yet, or you will move in a little bit before actually starting to attack. Other weapons with genuine 3m/2m/4m range still attack normally. I used to wonder why my ktn char using BS Nodachi sometimes doesn't attack while leveling at Cerberus, despite already standing at the spot that makes the range displayed as 3m, and have no attack cooldown, no skill in use, no nothing, completely free and available to do anything. Then someone else also said to me that Cosmic Sword (the 2hs dropped in Otsukimi event that is said/known to have "4m range") doesn't actually has 4m range but instead a little bit less. All those stuff led to this.
