I cleared it way back in the day and cleared it again just now, with 119 HP remaining.EmperorIng wrote:Hole of Druaga Lvl 3 seems like it'll be totally luck dependent on what Dristones you get, and with such a large maze I'm not sure how to best go about conserving air/HP and using Dristones.
Explore as much as you can first to find the key guardian, and the final guardian's entrance. If you find a room with only two colours of blocks, remember its location. Don't be afraid to use your change/destroy stones while searching for this room. Warp to this room repeatedly to stock up on health and Dristones before warping back to the final guardian's entrance. Try to keep equal numbers of change/destroy Dristones of each colour to optimize your inventory. At the bottom of the 2-colour room, just get rid of some of your less-useful stones and some of the change colour stones that are too numerous for the destroy stones of the same colour. I will go in to fight the guardian with maybe two HP+20% items, and the rest will be evenly-matched change/destroy stones, and you can defeat the guardian hardly needing to drill at all, except to move downwards slightly to fill the screen with more blocks.
