hmm, i cant remember of the top of my head, and i just done the seasons 4 times in a row :P I think you get the coupons either by unlocking the final reward in seasonal, or in the mail after you graduation.... not 100% sure at the moment without out doing seasonal again... ru-vid.comGzwLV4ddJxQ or its could be chapters of growth (black spirit quests) if you doing the express version of seasonal. sorry I don't have an exact answer at this time
I have seen a lot of people say a lot of different things, and it really can depend on how you plan to progress in the game... problems is, if you are new, you have not worked that out yet :P As a shai... I would exchange the Sol (shai's talent weapon) to a real version... so you have a Real Tet(4) sol you can look at upgrading to PEN (Always upgrade it safely if you do not have a back up). You can not buy this weapon (SOL) anywhere in the game, where as you have the option to buy any other item in the game... and as you progress you will see that 2 billion silver for a tet boss armour or weapons of the market become very manageable. only issue with the SOL path is, you can not upgrade it though the Jatina questlines (a alterative progression system grumpygreen.cricket/exchange-boss-gear/ ) some would say go for the helms, but as a shai that may look at DP set ups in game (if you go into PvP) the helm become complicated as you may wish to use a Zereth Helmet helm instead (special build ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NERn4leeXSo.html)... sooo You may wish to get the main hand weapon (kzarka florang) is your not planning on getting a Blackstar main hand, but you don't know yet? if not the SOL,or weapon, then the Glove or boots as you will be going one direction at pen (evasion if shai) so leeburs and muskins, where as you can select from any 2 of the helmers from the market and same with the armours (but most go rednose amour).. you will have limited availability for boots or gloves. But also, you can do the magnus guest and get a Real pen boss armour piece, So what you think is most important to you or more expensive to buy at pen, you will want to get later from the magnus quest line (can only get armours and not the weapon from magnus) yeah i know.. a lot of strange things to find out about. and i'm not good at typing :( I would say its not the end of the world if you go the wrong direction at this point, though its always nice to get to where you wanna go faster. TLDR; SOL maybe or gloves (personal shai perspective) it would need a whole video to explain fully >
