	==Overview==		==Overview==
	Various activities cause harmful magical energies to accumulate in your body. A small amount of magical contamination (a grey "% Contam" status) ~~are~~ harmless, and will dissipate over time without any further effect. Larger amounts of accumulated magic contamination (a yellow or red "Contam" status) will make you start to [[~~glow~~]] with magical contamination. Contamination is reported as a percent out of 300% maximum, internally tracked as 0-3000 points of contamination.		Various activities cause harmful magical energies to accumulate in your body.

Being at a severe contamination level makes you easier to hit and reveals you if [[Invisible]], similar to the [[Corona]] spell. It also lowers stealth and puts you at risk of [[Bad mutations]] and damaging explosions. The chance of exploding scales with contamination severity. Damage scales with player [[XL]]. Explosions at 200%+ contamination have increased radius and damage. When this happens, a mutation check will occur with a 1 in 5 chance of a single bad mutation or random [[Mutation]] (this is heavily weighted toward bad mutation outcomes). <!--if (x_chance_in_y(min(2000, you.magic_contamination), 3200-->

	==Major Changes ~~From Versions Prior To~~ [[0.34]]==		==Summary of Major Changes in [[0.34]] Compared to Prior Versions==
			For clarity, these Dev notes summarize the major changes detailed specifically above and should allow players to adjust their expectations from the old system:

	*Contam has been rescaled internally. 1000 is now the start of yellow, 2000 the start of red, and 3000 the absolute cap.		*Contam has been rescaled internally. 1000 is now the start of yellow, 2000 the start of red, and 3000 the absolute cap.

Line 65:		Line 68:
	*Contam explosions are possible at lower levels of contam than before, do significantly more damage (and ignore the player's AC), are non-elemental, and their base damage is based on the player's XL rather than the amount of contam. Yellow-tier explosions are radius 1, red are radius 2 and do more damage than yellow.		*Contam explosions are possible at lower levels of contam than before, do significantly more damage (and ignore the player's AC), are non-elemental, and their base damage is based on the player's XL rather than the amount of contam. Yellow-tier explosions are radius 1, red are radius 2 and do more damage than yellow.
	*Contam mutations no longer have a 50% chance to ignore rMut (along with a few other narrow interactions with mutation conflicts due to counting as 'forced'). This seems unnecessary, with rMut being both weaker and far rarer than when this system was first designed.		*Contam mutations no longer have a 50% chance to ignore rMut (along with a few other narrow interactions with mutation conflicts due to counting as 'forced'). This seems unnecessary, with rMut being both weaker and far rarer than when this system was first designed.
	*Contam is now listed as a percentage on the UI, while contaminated (near the Doom indicator). Yellow is 100% (ie: the start of actual negative gameplay effects), red is 200%, and the cap is 300%. While the specific number is admittedly unimportant for minor contam, it helps make the difference between low/high transparent to the player, and critically: allows ~~contam~~-costing spells to be transparent about what their risks are in the current moment.		*Contam is now listed as a percentage on the UI, while contaminated (near the Doom indicator).
