Just some things I could think of that might help the new players.
Some may also help "veteran players". :o:D
Being able to use skills such as Phoenix arrow, Poison zone & shadow snare in the same spot all the time, without having to drag your mouse there....
Choose the location where you want to aim, simply use the skill normally at that spot.
Make a macro, with nothing but the skill in it.
Now when you click that macro, you will use the skill automatically in that spot, re-select the spot by changing location with skill manually again.
You may only hit flagged people with AOE skills, for example if someone uses hide/fake death while having a *white name do not waste your time trying to AOE them, it wont work.
Flash skill from Yul will also not trigger if your enemy has a WHITE name, as this is an AOE skill aswell.
*Battleground effect is different.
Using AOE attacks on NPCs (including traps from yul) will never hit an enemy player wether he is flagged or not, so dont waste your time trying to break someones hide, or hitting them while being untargetted by doing that.
Use your tank (or strong healer) to break hide of enemys by AOEing them, also works good to damage while they are untargetable (i.e disparition), just dont hurt your friends too much.
Position your back against a wall quickly by running up to the wall, change your camera angle (in the position of which you want to turn) and click the "BACK" arrow key,
This will make your character turn to the location you're looking at while staying at the same location (the wall), avoid those annoying backstabbing othells.
Also saves you looking like a fool when you hold LEFT or RIGHT arrow key to turn your character manually :D
Fighting Sayha Seer?
Take notice of their hide skill, the one with an actual animation teleports them ~600 range to the back, quickly AOE/Flare that location to break their hide.
Use "Auto hotkey", AHK for short, to re-pogram your mouse/keyboard keys, i.e changing your keys so that ALT has the effect of CTRL and vice versa, any combination you can think of.
Can also be used to make macros if you do not own a keyboard/mouse with macro buttons, i.e holding down CTRL key to make PvPing easier.
Use your head and do not make a macro that is against the rules.

Adena?
Farm zaken & freya on alt chars, sell drops in either AH or NPC.
Farm Ceremony of Chaos AFK with as many chars as you can, each match is worth a few hundred thousand adena and requires no work.
Make your alts noblesse, and farm olympiad with them for the 10 match participation fee,
Simply do 10 matches, at the 1st day of next month you can calculate your points at olympiad NPC to get some free Marks of Battle, save those until you can buy the giant codex.
Dont forget to do the olympiad quest for free giants energy (2x giants energy per 10 matches, is a daily quest so you can finish this one on both Friday & Saturday for 4x GE (22m adena) for little to no work.
Key locations for lvling up fast/easily to 99 if you do not have someone to Powerlevel you;
85> 88~90: Harnak
88~90> 95 (Depending on gear/class): Fairy Settlement, more specific this spot;
https://i.imgur.com/lTWc4YN.jpg break the Cocoons by hitting them with skills/normal attacks by holding CTRL, AOE away.
95> 99: *Nornils cave (aka Boz Core), near kamael village
*Alternatively Hellbound if you can handle the monsters near beleths magic circle.
PvPing in Parnassus or similar? turn your graphics up.
The effects of talismans (longing etc) will activate once people leave their hide skills or login, this effect is visible through walls so you will be able to spot if someone is going out of hide.
Farming specific CC bosses (wealthy, armed etc)?
Simply PR and re-enter the instance if it is the wrong raid, the instance will reset and you can re-enter and try your luck again.
Trying to farm a specific raid (Michaela? Kechi? Veridan?) but unsure if you should make party?
Just enter the house in parnassus, take the quest from him, the NPC wil automatically give you the quest to the specific instancezone which is active at that moment.
Steam Corridor = Kechi
Emerald Square = Veridan
Coral Garden = Michaela
Simply abandon the quest if it is the wrong instancezone, and try again in an hour or two.
Yul;
Flash only works within low range of enemy/mobs, if you use it far away it has no effect.
If PvPing someone, rather than using it when near your enemy use it near a monster before your enemy has a chance to come close.
Flash will not work if your enemy has a WHITE name.
Yul/Feoh, using a keyboard with macro functions?
Program a macro to hold down "back" arrow key for half a second to reposition you, while also clicking the F button for "Quick evasion" or ""Magical Evasion" to teleport yourself to the front rather than the back.
Same thing can be used for Sayha seer hide skill.
Or simply use your mouse to reposition yourself, whatever you're more comfortable with.
Is not against the rules as seen here;

Othell;
While fake death, while standing up open a buy/sell/workshop window to be able to move your character instantly.
Normally the skill has a 1-2 second delay before being able to move.
Othell/Tyrr;
Use your skills to your advantage when running towards/away from someone, jump on monsters with your skills (Slow jump, shadow chase etc) to reach target point faster.
When you mention that the Chaos Ceremony would be good for Adena, would that be the reason?
Win a few Mark of Battle and then trade for something valuable? But that's so little.
