Generally I create compounds with the most elements and that's it XD
Today I used
CH4 - explodes
HNO3 - just rush it
CF4 (mistakenly written CH4) - slowing enemies
NCl3 - just support
2x SO2 - poison dmg
PH3 - flamethrower
O2 - for dmg and allowing CH4 to explode
Be2C - just support and big particles
2x MgCO3 - lasers
AlCl3 - just support
with this I got to inf71 and decided that I don't want to sit here for any more hours but I think I could get to 100+
