Your network has been upgraded, with your hub in particular being significantly improved: Your hub members may each access seven powers with zero loss in strength, while you in particular may use up to twelve without any power loss, and potentially up to twenty-five. For each power past the twelfth, you incur a slowly-increasing penalty in their strength, capping out at 50% for a full set.
Should you happen to also have Negentropy, then your hub members may access ten powers, and you may access the full twenty-five powers without any more loss in strength.
