Magic: The Gathering based Artifact (P.E.A.C.H)

[DMwithoutPC's]

The Manyform Blade

The four of you see a translucent long sword in front, inside the blade a symbol appears a two coloured Symbol. A red and blue dragon is depicted, and around it five colours flow. Red, blue, green, white, black. At the hilt of the sword, there are to twistable rings, which now show red and blue. If you twist one of the rings, a different colour shows and the symbol and colours on the blade shift.

Changing the position of one ring is a move action. All first affects are CL 8 all secondary effect CL 12
The first and secondary effect stack. When both the first and secondary effect are active, you gain +1 competence bonus to attack, damage, skill checks and ability checks.
If you change the colour of one of the rings while another effect is already active, it immediately stops. (for instance you are currently under effect of the Dimir colour combination, you shift the black ring to red to activate the Izzit colour combination, the Dimir effect ends immediately)

If you activate one colour combination more than 3(or 5, or 7) time in a month, the blade locks and you can only use that colour combination. These “charges” on the colour combinations fade away a month after originaly being triggered.

Players are not meant to immediately know all the code words, but gradually earn them over time. The UMD check to force the blade to work should in my opinion be either redicualy high or it shouldn’t be possible to do at all.

Is this balanced? And are the different powers equaly powerfull? This is my first attempt at homebrew so I actualy have no idea what I’m doing. I may have also butchered up the name of something..I have no idea what the Aura of this blade should be… or should it change with whatever Colour-Combination is activated?

Please P.e.a.c.h!

P.S. okay, I'm having trouble getting it in a table as I intended to. can anyone help me?

Edit: I still haven't found out how to place a table on the forum, but I put all the bonusses of the balde between spoilers so the page woudn't be so clustered.

P.P.S I'm not a native speaker, so please comment on grammar and spelling errors in a polite manner
