Why not make it get stronger faster? As in decrease the divider? Or make it freeze the target if it doesn't die, but only for 2 turns? However, besides Freeze what else can water do? If Zanz or one of you can come up with a new Water Spell then Freeze will have to do for now. The suggestion that it should generate quanta the more quanta you have is odd. Usually when I have a lot of quanta (ie 30+) I don't need all of it and I generate a large surplus. Why would you want more?
It makes your next ice bolt much stronger, this is what my idea come from, while fire have diminishing power, ice should in opposite
If you change its original effect to "Do 2 damage and for every 10
gain 2 more
", you lose it's damage increase for every 10
that you have. Unless you plan to replace its original freeze with that. Also, you have to have at least 50 initial
to increase the damage unless the next bolt is pretty much the same bolt.
50
= 18 damage
50
= 12 damage + 10
60
= 14 damage + 12
72
= 16 damage + 12
84
= 18 damage + 12
Even if that's implemented it doesn't really get all that much stronger. Also, how does fire have diminishing power? However, if you lower the divisor you'll allow it to grow faster;
Divisor = 8
50
= 18 damage
50
= 14 damage
64
= 18 damage
Divisor = 7
50
= 16 damage
56
= 18 damage
Divisor = 6
50
= 18 damage
As you can see if you go lower than 6 Ice Bolt will get stronger at an accelerated rate. However, this is only favorable for decks that produce excess quanta. Your idea is for decks that are usually low on quanta, but you should make the Ice Bolt free, as you're already going to produce
anyway.
