両手武器で攻撃して，棘付き鎧で膝蹴りして

　GIRGILLさんから「両手武器のオフハンド武器としてアーマーのスパイクが使えるらしい」というコメントががあったので，探してみた．

　If you attack only with your armor spikes during your turn (or use the armor spikes to make an attack of opportunity), you use them just like a regular weapon. If you use the full attack action, you can use armor spikes as either a primary light weapon or as an off-hand light weapon, even if you’re using a shield or using a two-handed weapon. In these latter two cases, you’re assumed to be kicking or kneeing your foe with your armor spikes.
