Actually this advice is badly written (for a professional report

), and not very elaborated, but nevertheless contains some good information. Unlike certain "other" "guides".
First, what he means is the cryptic armor. You get it from doing the 2nd cryptic tale quest, either the two armors when not giving them to the Warrior trainer, or the boots when you give him the armors. The boots have slightly less defense upgrade than the armor, but +30 is good and better than nothing. Without such armor, you will need to heal up and repot often, especially being a str/int build with low dex. If you get a FULL set, by making a second char in the account and going through the levels to do the cryptic quest again, or simply buying it, this gives you a very good protection, so you don't need to repot very often, if at all. It gives you +70 on defense, which is extremely good. You can afford to TANK mob packs of 7-9, instead of going at singles, wearing freaking ruddy wolf crap like the bots at beach. The 2nd cryptic quest actually is nothing but a lot of running forth and back, so not even much work to do. It's perhaps an hour of playing, if at all.
Second, the hawk is a NICE pet - however, it's not good at tanking. The bear is better at this, although he does less damage (has better dex=defense). And you can get it from lvl30 on.
The most important thing is to either have really LOTS of food for the pet (deer for hawks, duck for bears), or level it a little at Venom Swamp in auto fight mode while watching TV and looking every 10 minutes. Simply because the pets have no armor, and die easily if cornered from packs of their own level or higher. A hawk gets slaughtered at its basic level at beach, let alone Southern Plains, unless you feed it all the time (30 secs beach, 10 secs SP) when doing packs with AoEs. The bear does not that much better, but its food is cheaper, and it gets better earlier, and needs slightly less feeding.
However, the pet approach DOES help if tanking mobs (that means taking on 7-9 opponents instead of 1), because they draw mobs like flies that simply ignore you like the plague when you have already 3 mobs fighting you - and you need 9 to optimally use your AoE. The AoE attack is the one that has written "scatter" or "area effect" on the explanation when you mouse-over on the skill book panel that opens with pressing "B". It hits everything around you if it is near enough. Rod users have it with their level 10 skill book, others on the lvl25 ones, in the second or third place of the row.
What you do is running over the beach through crowds of mobs, they will follow first you, and then the hawk/bear. Then, you need to do a turn and run towards your pet since it will otherwise keep a little away from you, and usually get cornered and slaughtered (most attack the PET, not you). When you are under/next to the pet, click on the nearest enemy and use your AoE attack in the quickslots with its number. Easy if you understood the game, but there is an astonishing number of players who don't understand this using of group area attacks speeding up the levelling with factor 9. Problem is, the beach is so infested with bots, that new players look at what the bots do (whack single mobs one after the other, no skill attack), instead of what the real players do (gather packs of 7-9 mobs and zap them with the area skill attack).
So yes, it was not well-written, but it was a real advice. A lot better than telling people to grind by whacking single targets on horses.
