The AI wizard had these 3 values that increased with level:
a) Increase mana gained per turn
b) Increased value of spells in deck
c) Reinforcements on start of match
d?)Other possibilities could be simply tweaking up the various stats of a wizard such as there melee,defense,magic power,deck amount,boosting bonus, etc. This could possibly take the place of b), as you could incorporate more variety in their. Randomly allocating stats to wizards as you level up.
Perhaps with these 3 variables you could have something that scales up in a well paced way.
lvl 1 - AI on it's own (0a)(0b)(0c)
lvl 2 - AI with (1a)(.5b)(0c)
lvl 3 - AI with (2a)(1b)(0c)
lvl 4 - AI with (2a)(1b)(1c)
lvl 5 - AI with (3a)(1.5b)(1c)
lvl 6 - AI with (4a)(2b)(1c)
lvl 7 - AI with (4a)(2b)(2c)
lvl 8 - AI with (5a)(2.5b)(2c)
lvl16 - AI with (10a)(5b)(4c)
The variables themselves are not really specified....Just if you had a few variables to dial up as progression took place.
For me, the AI starting with creatures does grind with the game design of the game (the whole dynamic of starting with a wizard and building up an army of creatures)
I feel like something that scaled up to 30 levels might be a good place...of course you could have it go forever for whoever is up for that challenge but pacing it for about 30 levels to achieve something.
Perhaps for the experienced players, you could have an unlockable level cap were you can just jump in at level 10 or something of the sort as suggested by noworries (irc)
Sort of going beyond the scope for duel mode, but i think that theres a chance that something like this would totally appeal to the coop players if you added it. Think i might put up a new thread.
