Hack of Castlevania: Circle of the Moon


Circle of the Moon was a great Castlevania game, but the card system left something to be desired. Cards being dropped solely from enemies was less than desirable, since it meant that the main gimmick of the game was locked behind a game of dice. This mod makes the cards more accessible by placing them in specific locations around the world. Enemies who did drop cards now instead drop meat, as a nod to the classic style Castlevanias. Cards are generally placed in an ascending order of power; you won’t get big bone powers by searching the early areas.

Great way to fix one of CotM's most jarring flaws

Reviewed By: Tsukiyomaru0 on 08 Apr 2021

Originally grinding the cards was way too much of a pain, and some of them could become harder to get (after Adramelech, for one) due to monsters getting replaced, others had insanely low drop rate, and there were some exclusive to the Battle Arena that could be missed out permanently. So, this does fixes the major issue of dealing with RNG to get the card, but there are a few things that could have been done in addition to it, to further improve the DSS:

First is having the DSS combos automatically identified. Sure, one can use the codebreaker “42025688 0101″ and “00000063 0001″ to have that be done automatically, but there’s no reason the DSS effects should be hidden to begin, specially when there’s the off chance of being locked out of its reveal if you 100% the map and decide to try them out.

Second is making Venus+Griffin use less MP (down it from 4/second to 2/second or 1/second?), to make it “Increases INT” effect actually useful, because as is there is no point in using it since INT is mostly useful for MP regen.

Third would be making the Battle Arena lose its MP drain effect. Because having to rely on an exploit to use cards for a second (usually to summon) is not fun at all, and the area is already hard enough even if you somehow are able to use MP.

All in all, great hack for a great game.
