Blood Rush is multiplicative with True Steel.

Suppose you have 3x combo multiplier. Blood Rush will multiply crit chance by 1 + 1.65 * 3 = 5.95.

If you didn't add true steel then you will have 208.25 crit chance. If you added it you will have 333.2 crit chance. Let's round that down: 200% crits deal x4 damage without organ shatter and 2.5 * 1.9 * 2 - 1 =  8,5 with. 300% crits will deal x5.5 damage without organ shatter and 2.5 * 1.9 * 3 - 2 = 12.25 with. So it multiplies overall damage by 1.38/1.44 with/without organ shatter, or better than fraction mod. If you have two +90% elemental mods and add a third, you will multiply your overall damage by 3.7/2.8  = 1.32. So True Steel > third 90% elemental mod. Second 90% elemental is better though.
