So there won't be a sword that costs 49950 rupees halfway through the game?
It would be possible to get halfway through the game and become a total gamebreaker. That is, IF you're willing to spend months grinding 49,950 Rupees. Oh, and don't forget you have to pay 50 Rupees for a bait, then 5,000 Rupees for a casino membership card, plus be taxed for 75% of your winnings. On top of that, you are only allowed to win up to 2,000 Rupees per day after taxes. Damagewise, the Light Sword would deal 16 damage, enough to one-hit KO almost every single enemy. Furthermore, it would bypass all defense flags on enemies that ignore or block both swords and sword beams. So in theory, you could kill a Mirror Wizzrobe with it (6 hits with base HP). Oh, and the beams would home in on enemies and pierce them. Then ZC will crash due to piercing weapons randomly deciding to crash it.
Short answer to sum up the paragraph above: No.
Off-topic comment: I never liked that about Super Adventure Island 2 how you could get the Light Sword straight after the 3rd island if you used the casino to your advantage. Makes everything after that waaaaay too easy. After that, you NEVER have to change weapons again, save for using the Shovel in certain places and the Power Sword to get rid of those stones.
Speaking of ZC crashes, what exactly makes it crash with piercing weapons and segmented enemies? Because one I shot 4 Red Lanmolas with no problem the moment they spawned shooting to right, yet just a bit ago, I shot 4 segments off a Moldorm and got a crash. Is there a way to fix or prevent said crash or is it there to stay? All I could think of doing is making said enemies ignore piercing weapons, or simply don't make the sword and arrows pierce ever at the expense of making them much weaker. For the record, I had like a 100 segment Moldorm crash my game using a Super Bomb. Is it just safe to say to just stick with things like the candle and regular sword hits for said enemies?
