There are no free-to-play poisoned weapons in Runescape, no.
The overall best f2p Runescape weapon is actually a range weapon - Maple Longbow (sighted). It has a range bonus of over 100. The best f2p degradeable weapon is the Gravite 2h. Both are Dungeonneering weapons and need 45 Dungeonneering levels.
Nope :)
i have no idea what you are talking about if you mean poison weapons then you can only use poison on daggers or spears and you can also buy your own poison to put on your weapons besides that i don't know what you are talking about
you can keep all your items but you can't use them in F2P.
The only f2p dragon is the one from the quest "dragon slayer".
Weapons don't add to your defence bonuses. The best armour, however, would be full rune.
I think runescape is
Gravite shortbow.
No p2p only noob
