It has been confirmed that fireball is in and that it has 3 lvls of effectiveness Fireball, trap spell and Flamethrower. that was followed by Tod saying that all the spell will have as much flexibility so with this in mind i was trying to think up some realistic defensive spells. So far i have come up with one that basically works like a shield
lvl1 - quickly tapping the spell button puts up a transparent shield (like a one armed shield that a warrior would use but magical and cooler) that when hit by like a arrow sword , mace ect cracks and 3 consecutive ( if no follow up hits shield dissipates) hits break it dragon, troll, giant ect breaks it in one and knocks you back with severely reduced damage to mage.
lvl2 - if used while crouching creates a much stronger dome of force around you that uses 4 times as much magica at one time and can take 2 times as many hits.
lvl3- hold down ate activation button and it makes a slightly larger shield in front of you that takes the 4 or 1 hit like before but instead of breaking afterward it lasts until your magica runs out.
lvl4-dual wield same as the crouching spell but used when standing and activated with a single tap and a larger radius that enemies cant walk in or out of and no spells or attacks can leave 15 hits breaks it or 5 larger monster hits.
_not that i care to much about balance in a single player game every one has its nich and it makes sience that if you can actually land a hit on a mage the damage should be crippling but getting that hit should not be easy, this is balanced because the shield breaks quickly and when any but the lvl 1 or 3 is used you either cant attack or cant move_
this is just one of a few i thought out what are your ideas for realistic defensive spells?
