What is eth bug and other questions

[Ruvanal]

The Prefix on it is : Toxic 20.01 per second, Poison Duration 5 seconds
The Suffix on it is : Anthrax 8.39 Poison Damage per second, Poison Duration 6 seconds

20.01 + 8.39 = 28.40
5 + 6 = 11 seconds.

28.40 * 11 = 312.40 Total Poison Damage

There is a bug where the Display Screen caps the Poison Duration at 10 seconds so you don't get to see the real damage it does.

Because of this the game ends up (on the screen only!) with  28.40 * 10 = 284 Total Poison Damage

Don't ask me why the 284 gets displayed as 290.

The max poison duration on a single item is capped at 255 frames (10.2 seconds). So the duration that gets saved for that charm would actually be 10.2 seconds and not the 11 seconds that both paffixes together imply nor the 10 seconds that is the rounded value show for display purposes.

with 28.40 * 10 = 284 Total Poison Damage

should be 28.40*10.2=289.68
