Dragons SLAIN! Hurrah! I found a pattern I could stick to that made them much easier to kill and dodge, and so they were soon dead.
And then it was off on another wander around the castle opening areas I couldn’t previously get to, since I can now push big crates out of the way. Found some more HP/MP/heart upgrades, and then wandered into an area full of Ice Armour baddies and some sort of acid water. Eurgh.
