one way to make pearls is to go into the raid map for your level and farm in there another way is map 13 or the titansmashers that could be found in 8 and 9 map after sinking the karkinos

 

13-14-15 maps drakir hrell easy fast pearls also dont miss events good pearls crystalls and stuff also.

 

you most prob found out by now the warrior packs a punch, however, in the damage section of skills you can upgrade your damage prevention andrepair speed at your level you need both maxed. equaly in the ships castle you can get more damage prevention which is the key. i dont pay to play like you. as previously said events are the key and dont forget the scrolls. harp and cannon loader maxed out is a must you can gain a lot from wrecks.
the jolly roger event also known as the freedom event is ideal for you needs it provides a lot in the sense of flares amulets ect and buying the lion keys gets you more mojos which gets you more rewards
your cannons need to pack a punch however its not all doom and gloom at your present ship setup. with events let the big boys shoot first on addys all you do is just join in. crowns are more difficult but theres plenty of options make sure you do you warrior quest everyday especially for the sellsword which is a must have
