I will give RMU credit for trying to introduce the Size system into the game. I may not have liked it much as a character build issue, but for spells it would work wonderfully. This would allow like the shock bolt, lower level (1-3rd) elemental spells on the same charts as the normal spells, except with lower results and effects. One of the things that always frustrated me about the spells in RM is except the Magician's Shock Bolt, there was no low level damage spells. With the Size rules these can now be customized as with the same as the shock bolt which would allow for mini- fire, Ice, earth (pebbles) bolts at said (1-3 level). RM has one of the weakest mage type characters at lower level than any other system beyond the Wind Law or Spirit Mastery spell list. that is disappointing to me and adding these would do wonders for the system (Much like HARP) has done.
