Hi Bright,<br/><br/>If you do anything else in the round (move, handle something, whatever, you get one attack. To hit, roll 1d20+23 and if you hit you deal 1d10+18 damage.<br/><br/>If you only attack in the round, you get to attack twice. Make the first attack as above, and the second attack rolling to hit 1d20+18. The damage dice is still 1d10+18.<br/><br/>If you roll between a 14 and a 20 on a 1d20 you have a critical hit, which increases your damage for that hit to 2d10+36. You may then make a free Dazzling Display attempt against any adjacent creature  (see below).<br/><br/>In general you have the special option to make a Dazzling Display attempt as a full-round action. Dazzling Display – make a full-round Dazzling Display of combat prowess to give creatures within 30ft the shaken condition (-2 on attack rolls saving throws, skill checks, ability checks and vore checks). Roll 1d20+21, trying to beat DC10+targets hit dice+targets wisdom modifier. This effect lasts for 1 round plus one round for every 5 points by which the DC was beaten. This also works against animals and vermin.
