Since the effect is only a bypass for DR, I'd raise the attack to that of a regular beatstick. With that said, the effect seems to be really minor and situational. Maybe improve the effect instead?
Problem is, if I up it to a regular beatstick, the damage reduction becomes very minor. Two or three 5 | 3 Codas already attack with the strength of a dragon not accounting for regular. It's meant to be a scaled creature that increases as you place out more copies.
it should't be so powerful, the ability is a mix with momentum and spell damage, if i understand well it doesn't bypass dim shield, bonewall loses only one "bone", u get a normal freeze/death with ice shield/skull buckler, the
shields (upped and unupped) still block the damage with enough quanta, against fog shield and dusk mantle get a cumulative damage miss or regular?
until u don't make it aether u shouldn't have problem with fractal, almost every creature is strong with sopa, u can't do nothing about it, and in time fits well.
The ability is mediocre, a less effective momentum if you will. It is not spell damage, it is just tallied physical damage. It does not bypass Dimensional, Bone wall loses one counter, all Coda are frozen or are killed if the chance is triggered, the Dissipation Field will reduce the damage assuming quanta works, and Fog/Dusk calculate the attack as one hit for either a miss or a strike.
I feel like the card text could be improved. In game, where there is no notes, the card text will make less sense than "Attacks for all the creatures on the board". Would make SoW Coda interesting, if I'm interpreting correctly.
Perhaps "All Coda attack simultaneously"? That also brings up a point I had not thought of; should single effects count for the tally, or should all Coda have the effects for it to be counted?
Example; One Coda has Liquid Shadow; should the cumulative tally be vampire damage, or two different terminal attacks, one of regular Coda damage and one of vampiric Coda damage? I like the idea of each Coda manipulating the full terminal attack. Adrenaline on one Coda for four terminal attacks of 2 for a total of 8 will not be as effective as two or three Coda. This means only one Quintessence and Shard of Wisdom is necessary for the full damage to be converted to terminal spell damage. Possibly promotes use of Anubis.
