So if the old game had it's savefile stored in C:\Program Files (x86)\Old Game\SaveFiles you can copy them to C:\Program Files (x86)\steam\steamapps\common\Old Game\SaveFiles and there's a good chance they'll work. If it's an old game that keeps its save files under the same directory where the game is installed, then generally you can copy the save files to same place relative to where Steam has installed in the game. Unfortunately some games will use a different save game format and simply aren't compatible the Steam version. Other games will use the same file format but you'll need to copy them to a different place. Some games you won't have to do anything, they use the same save file format and use the same directory to store them in. Its regular attack deals damage in the same fashion as a Knot of Rust, while its ultimate attack (used when it has can increase the damage for you to use Dark Matter, it is also almost guaranteed to expend all of your stored damage - reserve summoning for when you do intend to blow that damage. There is a late game Esper, Shemhazai, whose moveset is based on the exact same mechanic. Using a Dark Matter will reset this, but it's clear to see that it is a very potent damage source. This item is much rarer, and deals damage equal to one third of the cumulative damage done by Knots of Rust, to a maximum of 60000 damage.


The main utility of Knots of Rust is to amplify the damage of another item, called Dark Matter. Also, the main reason to just continually use them is detailed below, as while the individual damage of a single Knot of Rust is puny, the results of continually using them can be reaped to a major benefit. No creature really resists the damage, and it beats sitting there either not attacking or worse healing the target. I find them useful as a gambit for a Bubbled character who isn't particularly gifted in the ranged damage department, or who otherwise can't use spells or skills to affect a particular enemy type due to resistances. The damage is equal to your current HP divided by a random number up to 10. Early game, they are thus pretty weak, and late game they aren't entirely potent. So it is best to use them with a character who has a high amount of HP. The damage of a Knot of Rust is based on your current HP.
