To strike such an extraordinaire performance you just have to make a pact with the devil.
- From the start dash to the town right next to you, use the herb.
- Move towards the southern village - dash through each and every battle but do not dash during your travel.
- Enter the village, replenish your health.
- Dash to the tower to your east and enter it.
- Dash through every floor, making sure to consume the herb when necessary.
- Dash back to the village, talk to the
fair villager terrible terrible demon thing.
- Once you leave the village move one step to the left* then dash up to the intersection to acquire your powers.
- Dash to the castle and through the boss fight.
*This is to make sure you don't lose time trying to dash through rock. I've had to throw away a couple runs for this. :/
If you still can't make it in 30 seconds, check your equipment - especially the weight statistic. The Gold Scudetto, for example, has the best defense at this point (+2) but carries a +15 to weight. Prefer the Merc Shield that trades 1 defense (enough to make it through) with 14 weight and throws 1 more evasion on top of it.
