Editing Poison (section)

=== Single poisons ===
The formula entropy posted for poison damage was...
<pre>P = 1 + (D-30)/30</pre>
... where '''P''' is the damage from poison, taken every 10 seconds, and '''D''' is the remaining duration in seconds. See the ''[[#General information|General information]]'' section above for the initial duration values.

However, this produced results that were slightly inaccurate, so we have to take rounding (in this case, truncating) into account. The derived formula that will produce accurate results is:
<pre>P = 1 + Truncate[(D-30)/30]</pre>

''Truncate'' means that if the result inside the square brackets is a fraction, always round down. By expanding the fraction, the 1's will cancel out, and we can simplify this with a few exceptions. For example, ...
<pre>P = Truncate(D/30)</pre>

... works, except for when D is between 0 and 30. Therefore, we must create a piecewise (multi-part conditional) function to account for all scenarios. The final formula for the amount of poison damage every 10 seconds is:
<pre>P =
     Truncate(D/30), when D = 0 or D >= 30
     1, when 0 < D < 30</pre>

From that formula, the remaining duration can be ''estimated'' by multiplying the interval damage (P) by 30. Even though this estimate will be distorted by the truncation of decimals and when P = 1, this formula is short and allows you to find the remaining duration (D) of the poison simply from watching how much health you are losing (P) every 10 seconds:
<pre>D (estimated) = 30P</pre>
