First Question:
So, I'm curious about making a jutsu that could allow for your Basic Attacks to count as X element for Y rounds. It would probably code as.. Deals Base Damage for 1d2 rounds, for an E-Rank for example. The point of doing it is to gain all of your Element specific bonuses on basic attacks for a number of rounds. The reason for this should be obvious, to save on chakra.
Second Question:
I'm curious about multiple use jutsu. It's similar to the above in some respects, but I'll generate a code for thinking. Deals Base Damage + 1d6 for 1d3 rounds. (1d3 rounds being uses). The point of this is similar to the above. It's effectively a buff, but gaining the ability to also count your basic attacks as the elemental type, plus the buffs damage.
Third Question:
How do Multi-attack roll jutsu work? There was mention of these under the DR per Hit entries, but not any rules regarding them.
