For example, an 8th-level lizardfolk monk with a Strength score of 17 has a base attack bonus of +7 (+1 for its 2 humanoid Hit Dice and +6 for its monk levels). The character has three natural weapons: two claws (1d4) and one bite (1d4). For this example, we'll assume the character also has the Multiattack feat.
With the full attack action, our example monk can make two unarmed attacks thanks to its +7 base attack bonus. After adding in the +3 bonus from the monk's Strength score of 17, our example character's unarmed attacks have the following attack bonuses: +10/+5. Thanks to the monk's class level and Strength score, damage for the unarmed strikes is 1d10+3.
The example monk also can attack with its claws and bite as secondary natural attacks at a -2 penalty (thanks to the character's Multiattack feat). Each natural weapon uses the character's +7 base attack bonus and +3 Strength modifier, except that the Strength bonus on damage is halved because these are secondary attacks: 2 claws +8 (1d4+1) and bite +8 (1d4+1).
As noted last week, there are no two-weapon or off-hand penalties for these attacks.
The example monk cannot use a flurry of blows because a flurry doesn't work with natural weaponry.
